Learning the friendly way

Currency strength shapes global trade, investment flows, and your real-world spending power. But strength isn’t just about flashy exchange rates. It’s backed by low inflation, investor trust, and governments that don’t spontaneously combust.

In this guide, we break down the top 10 strongest currencies in the world for 2025. You'll learn what drives their dominance, why some currencies outperform others, and what this means for markets, businesses, and travellers alike.

Spoiler: it's not always the ones you expect.

Before we begin: Currency strength is measured by exchange rate value against major currencies like the USD and GBP, combined with factors including economic stability, inflation rates, trade balances, and investor demand. 

The strongest currencies typically emerge from countries with sound fiscal policies, political stability, strong export economies, and substantial foreign reserves.

Top 10 strongest currencies in the world (2025 ranking)

The following currencies dominate global markets by exchange rate value against the USD and GBP. These rankings reflect the current market conditions at the time of writing.

1. Kuwaiti Dinar (KWD)

Exchange Rate: 1 KWD = 3.25 USD | 2.44 GBP

The Kuwaiti Dinar isn’t just strong - it’s consistently the world’s strongest. Fueled by vast oil reserves and a government that actually knows how to manage money, Kuwait punches well above its weight. A small population + massive petroleum wealth = eye-watering per capita income, and a currency that commands global respect.

Back in 2007, Kuwait ditched its US dollar peg for a currency basket, a bold move that gave it more control and resilience. Add in one of the largest sovereign wealth funds on the planet and a no-nonsense approach to spending oil money, and you’ve got a textbook case in currency strength.

2. Bahraini Dinar (BHD)

Exchange Rate: 1 BHD = 2.65 USD | 2.05 GBP

The Bahraini Dinar may not get the headlines, but it holds its ground thanks to a rock-solid USD peg and a thriving financial sector. As a gateway to the Gulf, Bahrain has built a reputation as a banking and investment hub, with the regulatory chops to back it up.

While oil still plays a role, the kingdom’s smart pivot into finance, tourism, and services has given the BHD more than one leg to stand on. Add close ties to Saudi Arabia and deep integration with the wider Gulf economy, and you've got a currency that’s quietly powerful and built to last.

3. Omani Rial (OMR)

Exchange Rate: 1 OMR = 2.60 USD | 1.92 GBP

Oman’s currency doesn’t just ride the oil wave - it’s powered by long-term vision. While crude still plays a role, the Omani Rial stands tall thanks to the country’s steady shift toward tourism, logistics, and manufacturing, all part of its ambitious Vision 2040 roadmap.

In a region known for volatility, Oman sets itself apart with political stability, disciplined fiscal policy, and a refreshingly balanced economic game plan. The result? A currency that’s not just strong, but built on more than just barrels.

4. Jordanian Dinar (JOD)

Exchange Rate: 1 JOD = ~1.41 USD | 1.08 GBP

Jordan doesn’t have oil fields or massive exports, but it does have one of the most stable currencies in the region. Pegged to the USD since 1995, the Jordanian Dinar has held firm through geopolitical shocks and economic headwinds.

What’s the secret? A central bank that plays it straight, a government that manages its books carefully, and a commitment to stability - even while supporting large refugee populations and navigating limited natural resources. In short: smart policy over raw power.

5. British Pound Sterling (GBP)

Exchange Rate: 1 GBP = 1.35 USD

As the world’s oldest currency still in circulation, the British Pound carries serious legacy power, but it’s more than just tradition. Backed by the UK’s diversified economy and London’s role as a global finance heavyweight, the pound remains one of the most widely held reserve currencies on the planet.

Let’s call a spade a spade. While Brexit brought its fair share of turbulence, the fundamentals haven’t changed: a strong legal system, deep capital markets, and world-class financial infrastructure keep the GBP firmly in the heavyweight league.

6. Cayman Islands Dollar (KYD)

Exchange Rate: 1 KYD = ~1.20 USD | 0.89 GBP

With more registered companies than people, the Cayman Islands punch way above their weight in global finance. The KYD benefits from this offshore powerhouse status, where financial services and tourism drive steady demand.

Pegged to the US dollar, the currency stays stable, while the islands’ investor-friendly regulations and tax perks keep international capital flowing. It’s a niche economy, but a well-oiled one, and the KYD reflects that strength.

7. Gibraltar Pound (GIP)

Exchange Rate: 1 GIP = 1 GBP (perfect parity)

The Gibraltar Pound holds a 1:1 peg with the British Pound, giving it the full weight of UK monetary policy with a distinctly local twist. It’s a territorial currency that does more than just mirror the GBP; it powers a compact but strategic economy.

Perched at the gateway to the Mediterranean, Gibraltar leverages its prime location and tight financial regulation to attract investment and business. The result? A stable, trusted currency backed by both geography and governance.

8. Swiss Franc (CHF)

Exchange Rate: 1 CHF = ~1.10 USD | 0.88 GBP

Listen, the Swiss Franc doesn’t just symbolise stability - it sets the standard. Backed by political neutrality, low inflation, and one of the world’s most trusted banking systems, the CHF is where capital goes when things get shaky.

The Swiss National Bank’s conservative approach and Switzerland’s strict fiscal discipline make the Franc a magnet for investors seeking security. In times of global turbulence, the CHF doesn’t flinch, it holds.

9. Euro (EUR)

Exchange Rate: 1 EUR = ~1.05 USD | 0.84 GBP

The Euro ties together 20 EU countries under one economic flag, creating a currency backed by a collective economy even bigger than the U.S. Despite political bumps and economic contrasts across member states, the EUR holds its ground as the world’s second-most traded currency.

What keeps it strong? The European Central Bank’s monetary oversight, the eurozone’s combined economic weight, and the Euro’s deep role in global trade and reserves. It’s not just shared money, it’s shared strength.

10. United States Dollar (USD)

The global standard

The USD may not top the exchange rate charts, but some might argue that it owns the global stage. Involved in nearly 88% of all forex trades and held as the primary reserve currency by central banks worldwide, the dollar is the backbone of international finance.

Its strength isn’t necessarily about value per unit, it’s about reach. From oil pricing to cross-border deals, the USD is the language of global trade, powered by the world’s largest economy and the deepest capital markets on earth.

What makes a currency strong?

Strong currencies aren’t just about optics: they’re built on trust, economic fundamentals, and global demand. The world’s top performers all share a few key traits that keep investors confident and capital flowing.

So, what drives currency strength?

At the core, it’s about stability and credibility. Countries with steady politics, transparent institutions, and clear economic policies tend to attract global investment. High interest rates - when balanced with low inflation - pull in foreign capital, while low inflation protects the currency’s real-world value.

Trade matters too. When a country exports more than it imports, global buyers need the local currency, driving demand and pushing up value. Large foreign exchange reserves also give central banks firepower to defend their currency when markets wobble.

Debt is another big one. Lower debt-to-GDP ratios signal fiscal discipline and room to manoeuvre during economic shocks, key ingredients for long-term currency trust.

Pegged vs floating exchange rates

Currencies typically fall into two camps: pegged or floating.

• Pegged currencies (like the Bahraini Dinar or Jordanian Dinar) lock their value to another, usually the US dollar - yes, just like stablecoins. This provides predictability for trade and investment, but demands strict monetary control and healthy reserves to keep the peg in place.
  
  
• Floating currencies (like the Swiss Franc or British Pound) let market forces do the work. That means more volatility, but also more flexibility when shocks hit, if central banks know what they’re doing.

Both systems have their strengths. The key is whether the country can maintain trust through smart policy, solid reserves, and consistent economic performance.

Honourable mentions

While these currencies didn’t make the top 10, they still offer stability, liquidity and are backed by solid economic fundamentals.

These currencies benefit from resource wealth, strong institutions, or strategic economic positions that support their value in global markets.

How is currency value measured?

Currency strength isn’t measured in a vacuum, it’s always relative. Exchange rates compare one currency against another (like USD/EUR), and those prices shift constantly based on supply, demand, and investor sentiment.

In deep, liquid markets, these rates reflect what the world thinks about a country’s economy, stability, and future outlook. Big trades happen fast and without much friction because major currencies have enough volume to absorb them.

Central banks keep a close eye on all this. In floating systems, they rarely intervene unless things get choppy. But day to day, it’s market forces that drive currency values, shaped by fundamentals and the collective mood of global finance.

What is the most stable currency in the world?

No drama, no surprises: the Swiss Franc is the gold standard for currency stability. Backed by political neutrality, low inflation, and ultra-consistent monetary policy, the CHF has earned its reputation as a safe-haven asset.

The Swiss National Bank doesn’t chase headlines. Instead, it focuses on one thing: price stability. And it’s done that with surgical precision for decades. Add in a political system designed for consensus and slow, steady change, and you get a currency that markets trust, especially when things get rough.

In times of crisis, global capital flows to the Franc. That trust? It reinforces the CHF’s strength, year after year.

What is the most traded currency in the world?

Likely no surprises here either: The dollar is (currently) the backbone of the world’s financial system. Accounting for nearly 90% of all forex trading, it’s the go-to for everything from central bank reserves to international commodity pricing.

Around 60% of global foreign exchange reserves are held in USD, and even countries with no direct US ties use the dollar to price and settle trades. This widespread use creates powerful network effects - the more the dollar flows, the more stable and liquid it becomes, drawing in even more users.

It’s a self-reinforcing cycle, fueled by the sheer size and strength of the US economy.

Conclusion 

Currency strength goes beyond daily exchange rates. It’s a reflection of a nation’s economic health, fiscal discipline, and political stability. While rates bounce around day-to-day, the core drivers of strength are built to last.

Knowing what fuels currency power isn’t just academic, it’s critical for smart investing, international business, and even planning your next trip. The strongest currencies aren’t just the ones with high numbers, they’re the ones backed by solid economics and trusted institutions that keep value steady over time.

Imagine you walk into a grocery store with only $20 in your wallet. You want fruit, bread, milk, and maybe a treat. But as you add items to your basket, you realize you can’t afford everything. You need to make a choice. That everyday dilemma is scarcity in action.

Scarcity is the fundamental economic problem: people have unlimited wants, but our pool of resources (money, raw materials, and of course, time) is limited. Because of this imbalance, every decision comes with trade-offs. Scarcity is not just about wealth or poverty; it shapes the psychology of markets and investments, and understanding it can give you a sharper edge in your decisions. So, join us and let’s tap into the core of economics.

What Is Scarcity? Key Takeaways

Economics tells us scarcity is the lack of plentiful resources in comparison to theoretically infinite wants. This term can be boiled down to this simple definition: any resource with a non-zero cost associated with consuming it means that it's scarce to some degree.

The concept of scarcity often drives people to make decisions about how they want their resources allocated so that everyone can satisfy not just their basic needs, but also additional wants whenever they can.

• Scarcity means limited resources vs. unlimited wants.
  
  
• It’s the foundation of supply and demand, influencing prices in every market.
  
  
• Scarcity affects everyone, not just those with fewer resources.
  
  
• It forces individuals, businesses, and governments to make decisions about allocation.
  
  
• Every choice under scarcity involves opportunity cost, the value of the next best alternative.
  

The Economic Foundation of Scarcity

In 1932, Economist Lionel Robbins gave the most cited definition: “Economics is the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses.” This definition highlights the key concept: people want more than the economy can provide. Resources are finite. Choices must be made about how to use them.

Scarcity is tied to supply and demand. If a product is scarce and demand remains high, the price usually rises. For example, when microchips became scarce during the pandemic, the cost of everything from laptops to cars increased. This basic economic problem applies in any given scenario: whether you’re a student managing study time, a household balancing bills, or a government allocating healthcare budgets, scarcity forces tough decisions.

Types of Scarcity

Economists classify scarcity into three major types:

• Absolute Scarcity: Resources that are genuinely finite, such as oil, rare earth minerals, or land in city centers. Once they are gone, they cannot be replenished.
  
  
• Relative Scarcity: Resources that may exist in abundance overall but are limited by distribution or production. For example, in water-rich areas, people seemingly never have to worry about running out of water as the supply is limitless while in other areas people have no access to clean running water. In water-scarce areas, the costs increase, and authorities and citizens have to decide how to efficiently allocate resources. The same can be said about land prices when you compare the prices of properties in the countryside versus an affluent city center. Authorities cannot simply produce more land, so the prices increase alongside demand.
  
  
• Artificial Scarcity: Created by humans, often in markets. Luxury brands limit production to increase exclusivity, or companies use patents to control product availability. Concert tickets are another example. Limited supply is maintained even though more could be produced.

Real-World Examples of Scarcity Throughout History

Scarcity is not abstract; it shapes all markets:

• Modern Housing Markets: In cities like London or New York, limited land and high demand create soaring property prices, a textbook case of relative scarcity.
• Concert Tickets: Popular events sell out in minutes, not necessarily because of physical limits but because scarcity marketing drives urgency.
• Ethereum Fee Burn: Since 2021, Ethereum burns a portion of every transaction fee, reducing the total supply. This scarcity mechanism can increase the value of ETH over time, illustrating how limited supply and high demand influence markets in the crypto world.

What Are the Three Causes of Scarcity?

Scarcity is a term that economists use to describe the limited availability of a good or resource, turning some things that might have once been abundant into scarce resources. The root causes can be broken down into three categories: 

Demand-induced scarcity: when consumer demand outweighs supply, e.g. face masks in the wake of the global pandemic. 

Supply-induced scarcity: This happens when outside forces make a resource less attainable, decreasing supply with little impact on demand. E.g. commonly with a natural resource, such as water in a drought.

Structural scarcity: When some have greater access to a resource than others. Structural scarcity often happens because of political or economic reasons.

The Psychology of Scarcity

Scarcity doesn’t just change markets; it changes how people think. Behavioral economists describe the scarcity effect. This is when people perceive something as scarce, its perceived value increases. That’s why limited-edition sneakers sell for thousands.

Scarcity also fuels FOMO (Fear of Missing Out); the opposite of FUD (fear, uncertainty, and doubt). Marketers use countdown timers, “only 3 left in stock” alerts, and exclusive drops to trigger quick decisions. While artificial, these tactics rely on the same psychological mechanisms as natural scarcity. At a personal level, scarcity of time or money can narrow focus, sometimes leading to poorer decisions such as payday loan cycles or unhealthy food choices when stressed.

Scarcity in the Natural World

We usually think of scarce resources as natural resources that exist on Earth without humankind's intervention, such as gas, coal, or water. These commodities often have a limited supply. Food can be produced, for example, but the fuel we need to move it around is gone forever once we use it.

The scarcity of natural resources also generally increases with growing populations. This brings in relative scarcity, which refers to the scarcity of a resource in one region while it may be more abundant in another. This concept applies not only to commodities but also to services that rely on these resources.

Scarcity in the Economy

Economic scarcity occurs when the quantity individuals want to purchase exceeds the amount available for trade, driving up its monetary value. For instance, Bitcoin, with its limited supply of 21 million coins, illustrates this concept. As the coins become scarcer, their value grows higher, making it a potentially valuable choice for traders.

Scarcity vs Shortage

While scarcity and shortage might sound like interchangeable terms, there are several key differences between these terms and very different causes. 

Scarcity looks at the limited availability of something that cannot be replenished, natural resources for example. On the other hand, a shortage refers to a market phenomenon where the demand for something is greater than the quantity supplied at the market price.

When the market is balanced, there is an equal amount of supply and demand for a product. If these become unbalanced, we can have a shortage. Several things can create this scenario.

Firstly, it could be a result of increased demand. This is rarely permanent and can easily be reproduced. Secondly, it could be a result of a decreased supply. If the costs of a product increase causing the manufacturers to create less, and the demand stays the same, this will result in a shortage. In both instances, changes to the market can fix this. 

The main difference between scarcity and shortages is that shortages can usually be solved by altering supply and demand. With scarcity, however, there is a limit on the amount of a resource available with little that can be done to fix this problem. 

Living with Scarcity: Conclusion

Scarcity is the foundation of economics because it forces human decisions about how to use limited resources. It influences markets, prices, and behavior, from choosing groceries to managing global energy supplies.

While scarcity cannot be eliminated, societies can manage it through innovation, trade, and better information. Recognizing opportunity costs and making informed decisions helps individuals and governments alike.

Ultimately, scarcity reminds us one thing, which is that value comes from limits… and that every choice matters.

Bitcoin has become a household name around the world, for very good reasons. The same way gold became the standard of currency, bitcoin is doing the same. With the rise of gold, we also saw a gold rush, as people flocked to the mines to find every flake of gold they could. Something similar is happening to bitcoin right now as the cryptocurrency mining rush has begun, with the world hiking up their ASIC miners to process as fast as possible.

Especially with talk of Elon Musk considering reinstating Bitcoin payments once the carbon emissions and energy consumption associated with bitcoin mining are decreased. But why the sudden rush? it is not just another bubble, it is about global economic sustainability and excelling cryptocurrencies. 

Where is the Bitcoin mining rush happening?

Although the whole world may be captivated by the potential of cryptocurrency, China has always been a top contender for miners. Despite the repeat FUD spreading around China and its acceptance of digital currency, China bitcoin mining once accounted for more than 70% of mining power. But this summer's sweeping crackdown in China has greatly increased profits for miners outside of the world's second-largest economy, with counties such as the USA, Russia, and Iran making up for lost blocks. These regulations won’t stop Chinese miners from doing what they need, they just may no longer be doing it within the borders of China. 

It was 2 months ago that Beijing made moves to crack down on cryptocurrency. One of the steps was halting the supply of power to bitcoin farms, giving Chinese miners no choice but to pack their bags for more crypto-friendly countries. Chinese researchers express data portraying excess use of electricity consumption, especially in these stressful times. 

What is Chinas’ issue with digital currency mining?

China has had numerous issues with cryptocurrencies over the years, first stating they didn’t want their economic wealth flooding into a global currency. They have potentially solved this problem as they announce their own digital currency created by a group of specialist. China’s digital currency, the digital yuan, is controlled by its central bank which will issue the new currency. Now they may have created a digital form of currency, but it is nowhere near cryptocurrency, aside from some computational comparisons. China plans to strip away the anonymity so beloved within Blockchain, and inside track and control where their digital currency goes. Nonetheless, their first issue has been fixed, so what is their problem now?

Supposably carbon emissions and energy consumption in the country are rising, due to cryptocurrency, not the masses staying at home. Regardless of if their reasoning and intent are pure, we know carbon emission due to cryptocurrency is a very real and impending issue. This theory has been confirmed by Tesla's Elon Musk halting bitcoin payments until the carbon emission issue is resolved, rightfully so as the guy selling low carbon emission electric cars. 

What is next for Chinese miners?

Bitcoin mining is one of the most lucrative major industries in the world, yet many people don't know that Bitcoin mining generates just as much revenue as gold and silver extraction. The old Gold Rush might be waning, but Bitcoin miners are reaping the rewards of a new gold rush. The current generation shows entrepreneurial spirit unlike many before it, especially as the online era continues to expand.

They see the market and trend associated with cryptocurrency and are ensuring they are involved in as many ways as possible. From trading on an exchange, accepting bitcoin for services, or using their computer to mine crypto. Blockchain technology is proving to be a leader in so many industries, even emission avoidance, so no issue should or will stop people from accepting and collecting it. 

Renewable energy countries 

The solution to China's electricity and energy consumption issues is not to stop cryptocurrency mining altogether, but rather for miners to move to more power conscious countries. This may not be so appealing for China itself, but it is proving to be the best option for miners. Miners may take a lot of energy and computer processing, but they also run very hot.

So miners are looking for a country with a cheaper electricity cost to move to, with the added benefit of them being cold for an additional cooling process. Most countries that use renewable energy find their costs a lot lower than those that do not, this was even seen in China. Miners would run to the mountains of Sichuan, where abundant hydroelectric power made electricity services costs exceptionally cheaper per unit. 

Colder climates like Germany, Sweden, and Scotland are becoming increasingly more desirable countries of residency for crypto miners. Sweden is planning to be the world's first fossil fuel free country by the year 2040. Denmark has broken a wind power record, showing 43% of its electricity consumption being covered by wind; they also plan to be fossil fuel free by 2050.

Germany is a leader in renewable energy, and in the first half of 2018 they proved that, by producing enough renewable electricity to power every household in the country for a year. Scotland is also joining the ranks of the greatest renewable energy countries. Scotland plans to build the worlds’ largest floating wind turbine farm, as wind power can generate 98% of Scotland’s electricity needs.

These are all brilliant, and cold countries can easily fit the needs of any cryptocurrency miner, with cheaper watts and a cooler climate to cut down even more on watts. 

Risk of regulations

While the above-mentioned countries are great candidates for cryptocurrency and bitcoin mining, there are other problems to be wary of. Crypto regulations are just an issue among crypto miners, but also for exchange services. Each country has taken its own approach to enforcing cryptocurrency into its economy, but some may be trickier than others. VISAs are also another thing to take into consideration. Holiday VISAs are easily acquired, but moving your entire mining farm across borders may not be as easy.

Would you need a work VISA? A residency VISA? That is up to each miner to find out. Germany has shown positive sentiment to cryptocurrency, considering it as legal tender, and allowing institutional funds to hold up to 20% in cryptocurrency. Denmark and Scotland have also shown interest in cryptocurrencies, considering tax policies to help their native traders and the economy. Miners may be susceptible to taxation, and VISA regulations, but they do not have to worry about being in a country that wants to get rid of cryptocurrency. This alone, in addition to renewable energy, are benefits to any crypto enthusiast. 

Bettering the blockchain process

Not only does renewable energy mining save the world and miners money, but it also advances blockchain in general. Projects and people are more likely to accept cryptocurrency and Blockchain when it doesn’t have such a high economic and environmental burden. Using a terawatt of renewable energy is far more efficient and cost-effective than using electricity powered by fossil fuels and coal. With the bitcoin and cryptocurrency mining rush continuing to rally up troops, we in the community need to make conscious decisions for both cryptocurrency and our planet.

The process of excelling bitcoin and bitcoin mining starts at finding a computing process that consumes less energy. Whether the miners in China, or around the world, have this intent is not the issue, as long as the rest of the planet pushes them towards more eco-friendly options. It doesn’t start with the miners, they are simply the suppliers, its starts with what we demand, as seen by Mr. Musk. Let us make better choices for Blockchain, earth, and our national economies. 

In a world where every crypto project claims to be 'revolutionary,' Ethereum actually walks the talk, successfully changing how we think about the internet, finance, and digital ownership.

Conceived by Vitalik Buterin in 2013 and launched in 2015, Ethereum expanded the possibilities of blockchain technology beyond simple currency transactions, introducing a world where apps can run exactly as programmed, without censorship or third-party interference.

While Bitcoin introduced us to digital money, Ethereum brought us programmable money (and much more, for the record). You may have heard it being referred to as the world's computer, this is because it allows developers to build and deploy decentralised applications (dapps) that can transform industries from finance to art, gaming to governance.

In this comprehensive guide, we'll explore what makes Ethereum special, how it works beneath the surface, and why it continues to be at the forefront of the blockchain revolution. Whether you're completely new to the concept or looking to deepen your understanding, we'll break down everything from smart contracts to NFTs, the shift to Ethereum 2.0, and what the future might hold for this groundbreaking technology.

What is Ethereum? Explained simply

Think of Ethereum as a global, open-source platform for decentralised applications. While Bitcoin is primarily designed to be digital money, Ethereum is built to be a development platform, a foundation upon which developers can create new applications that no single entity controls.

The easiest way to understand Ethereum is to compare it to your smartphone's operating system. Just as iOS or Android provides a platform for developers to build mobile apps, Ethereum provides a platform for developers to build decentralised apps. These apps run on a network of thousands of computers around the world rather than on centralised servers owned by Google or Amazon.

Ethereum is often described as a "world computer" because it's essentially a massive, distributed computing system that belongs to everyone and no one at the same time. Unlike traditional computers controlled by individuals or companies, this world computer runs programs (called smart contracts) that execute exactly as written, without the possibility of censorship, downtime, or third-party interference.

As a "second-generation blockchain," Ethereum took Bitcoin's innovation (a decentralised ledger) and added programmability to it. This advancement opened up a universe of possibilities beyond simple value transfer, allowing for complex financial instruments, digital ownership records, and even autonomous organisations to exist on the blockchain.

How Ethereum works

At its foundation, Ethereum builds on the same blockchain technology that powers Bitcoin. A blockchain is essentially a chain of blocks, where each block contains a record of transactions. What makes it special is that this record is maintained by thousands of computers (nodes) around the world rather than by a central authority like a bank.

What are smart contracts?

Where Ethereum truly shines is with smart contracts. Think of smart contracts as digital agreements that automatically execute when predefined conditions are met, like a vending machine that delivers your soda when you insert the right amount of money. These contracts are:

• Self-executing: They run automatically when conditions are met
• Immutable: Once deployed, they can't be changed
• Transparent: Anyone can verify the contract's code
• Trustless: You don't need to trust a third party; the code is the guarantee

What is Ether (ETH)?

Ether (ETH) is the native cryptocurrency of the Ethereum network. It serves two important purposes:

1. As a digital currency that can be sent instantly to anyone, anywhere in the world
2. As "fuel" for running smart contracts and transactions on the network

What are gas fees?

This brings us to gas fees. Just as your car needs gas to run, Ethereum operations need "gas" to execute. Gas fees are small amounts of ETH (measured in “gwei,” a subunit of ETH) paid to network participants who contribute computing power to validate transactions. These fees help keep the network secure and prevent spam or infinitely running programs from clogging the system.

When the network gets busy, gas prices rise because there's limited space in each block, making Ethereum transactions sometimes expensive during peak times.

What are token standards?

Ethereum (truly) revolutionised the cryptocurrency ecosystem with its token standards. These are frameworks that define how digital assets behave on the network. 

Ethereum’s token standards are like architectural blueprints in the sense that they provide a consistent design that developers can follow to ensure every structure (token) integrates seamlessly into the broader city (Ethereum ecosystem).

The 3 main Ethereum token standards:

• ERC-20: Created the template for fungible (interchangeable) tokens, making it easy to create new tokens without building a new blockchain (although adoption still depends on design and demand). This standard powers thousands of tokens, including major stablecoins like USDC and most DeFi tokens.
• ERC-721: ERC-721 was the first standard to define non-fungible tokens on Ethereum,, however today there are additional NFT-related standards, such as ERC-2981 for royalties. This standard made possible the digital art revolution, powering collections like CryptoPunks and Bored Ape Yacht Club.
• ERC-1155: ERC-1155, introduced by Enjin, is ideal for games and metaverse applications where users need both fungible and non-fungible currencies and unique collectibles. 

These standards transformed crypto by creating massive interoperability, all of a sudden tokens built on Ethereum worked instantly with hundreds of wallets and exchanges. This "plug-and-play" functionality dramatically accelerated innovation and adoption.

Ethereum's token standards have become so influential that even competing blockchains implement compatibility with them, essentially making them the industry's universal language for digital assets.

The Ethereum ecosystem

Ethereum's true power lies in its vibrant ecosystem that continues to expand in exciting ways:

Decentralised applications (dapps) 

These are applications built on Ethereum that connect users and providers directly without any intermediary organisations controlling the service. Some popular examples include:

• Uniswap: A decentralised exchange for trading tokens
• Aave: A lending and borrowing platform
• OpenSea: A marketplace for digital assets

DeFi (decentralised finance) 

Perhaps Ethereum's most transformative impact has been in finance. DeFi applications recreate traditional financial services like lending, borrowing, and trading, but without banks or brokers. 

Instead, they use smart contracts to create protocols that operate exactly as programmed. By April 2025, the total value locked in DeFi protocols has grown to tens of billions of dollars, demonstrating significant adoption of these new financial tools.

NFTs (Non-Fungible Tokens) 

NFTs represent unique digital assets - from artwork to music to virtual real estate. Unlike cryptocurrencies, where each coin is identical, each NFT has distinct properties that make it one-of-a-kind. 

This technology has revolutionised digital art by enabling verifiable ownership and scarcity for digital creations, leading to an explosion in creative expression and new income opportunities for artists.

DAOs (Decentralised Autonomous Organisations) 

DAOs are internet-native organisations collectively owned and managed by their members. They operate based on rules encoded in smart contracts: members vote on decisions, and the outcomes are automatically executed by code. From investment clubs to charitable foundations, DAOs are reimagining how we organise and collaborate.

Ethereum 2.0 and The Merge

In 2022, Ethereum underwent its most significant upgrade since launch, transitioning from Proof of Work (PoW) to Proof of Stake (PoS) consensus with an event known as "The Merge." This transformation addressed several key challenges:

• Environmental impact 

The original Ethereum (like Bitcoin) used Proof of Work, requiring massive computing power and electricity consumption. The switch to Proof of Stake reduced Ethereum's energy usage by approximately 99.95%, addressing one of the biggest criticisms of blockchain technology.

• Scalability 

Ethereum's popularity led to network congestion and high transaction fees. The move to PoS laid the groundwork for future scaling solutions, including sharding (a method of splitting the network into parallel segments to increase transaction throughput dramatically).

• Staking opportunities 

Under the new system, users can "stake" their ETH (lock it up as collateral) to help secure the network and earn rewards, typically 3-5% annually. This provides a way for ETH holders to earn passive income while contributing to network security.

Ethereum vs other blockchains

Ethereum vs Bitcoin 

While both use blockchain technology, they serve different purposes:

• Bitcoin: Primarily a store of value and medium of exchange
• Ethereum: A platform for building applications and executing smart contracts

Ethereum killers

Several competing platforms have emerged, each claiming to solve Ethereum's challenges:

• Solana: Offers higher transaction speeds and lower costs
• Cardano: Focuses on academic research and formal verification
• Polkadot: Created by an Ethereum co-founder to enable cross-chain interoperability
• Avalanche: Emphasises high throughput and fast finality

Of course, these benefits can come with trade-offs in scalability and ease of use.

Ethereum's advantages 

Despite strong competition, Ethereum maintains significant advantages:

• First-mover advantage and massive developer community
• Highest security due to its large, distributed network
• Most extensive ecosystem of applications and tools
• Strong network effects and brand recognition

Risks and considerations

While Ethereum offers exciting possibilities, as with anything, it's important to understand the risks:

Price volatility 

ETH, like most cryptocurrencies, experiences significant price swings. Since 2015, it has seen both 90% drawdowns and 1000%+ gains. 

Security concerns 

While the core Ethereum protocol has proven secure, smart contracts can contain bugs or vulnerabilities. High-profile hacks have resulted in hundreds of millions of dollars in losses over the years.

Regulatory uncertainty 

Governments worldwide are still determining how to regulate cryptocurrencies and decentralised finance. Regulatory changes could impact certain applications or use cases.

Technical challenges 

Despite improvements, Ethereum still faces challenges with scaling to meet global demand, maintaining decentralisation, and providing a seamless user experience.

The future of Ethereum

Ethereum's roadmap continues to evolve with several key developments anticipated:

Scaling solutions: "Sharding" is expected to significantly increase Ethereum's capacity by splitting the network into parallel segments, potentially enabling thousands of transactions per second.

Layer 2 growth: Solutions built on top of Ethereum like Optimism, Arbitrum, and Polygon continue to gain traction, offering lower fees and faster transactions while maintaining security by settling transactions on the main Ethereum chain.

Industry adoption: Major companies from finance to entertainment are exploring Ethereum for applications ranging from supply chain tracking to royalty distribution. Enterprise adoption is expected to accelerate as scalability improves.

Web3 integration: The vision of Web3 - a more decentralised internet where users control their own data and digital identities - is being built largely on Ethereum. This could fundamentally change how we interact with online services.

How to buy Ethereum (ETH)

If you'd like to become involved in the Ethereum platform and own the digital asset that fuels the network, you will need to purchase ETH through a trusted crypto exchange platform and set up an Ethereum wallet. 

Offering a secure and convenient solution, buying and selling ETH through your Tap app is easier than you might think. With several payment options and a quick verification check, you can start trading, using or hodling ETH from your unique wallet in a matter of minutes. 

Final thoughts: why Ethereum matters

Ethereum represents one of the most ambitious technological experiments of our time - an attempt to rebuild the very foundations of how we transact, collaborate, and create online. By removing intermediaries and enabling direct peer-to-peer interactions, Ethereum challenges traditional power structures and creates new possibilities for human coordination.

Whether Ethereum ultimately fulfils its vision of becoming the settlement layer for a new, decentralised internet depends on how it addresses its remaining challenges around scalability, usability, and regulation. But its impact is already undeniable, having spawned entire industries from DeFi to NFTs and inspired a generation of developers to rethink what's possible with blockchain technology.

The most fascinating aspect of Ethereum may be that we're still in the early chapters of its story. Like the early internet in the 1990s, we can see the potential but can't yet imagine all the ways this technology will transform our world in the decades to come.

As you navigate the waters of the cryptocurrency market you're likely to come across a term called "coin burning". In this article, we're exploring the process used to manage the token supply of projects, a means for companies to manually alter the supply (and thereby demand) of a token's circulating supply. While not adopted by every project, coin burning has proven over the years to be successful in increasing the price of a digital currency.

What Is A Coin Burn

Diving right in, a coin burn is the process of removing a certain number of tokens from circulation by sending them to an invalid address, a "black hole" of sorts. This process is written into the project's code and implemented at various increments as outlined in the whitepaper. While Bitcoin doesn't make use of coin burning, many projects on the Ethereum network, particularly ERC-20 tokens, have been known to implement it.

Through the use of a smart contract, also known as a burn function, the network would remove a specified number of tokens from circulation, decreasing the total supply and thereby (hopefully) increasing the demand. Coin burns have been known to lead to an increase in price, as the supply-demand ratio is altered.

An Example Of Coin Burning

A top 10 cryptocurrency project underwent a coin burn last year that is believed to be the biggest layer 1 token burn to date. 88.7 million LUNA, the native coin to the Terra project, were burned in November 2021 following a vote by the community. This was effectively worth $4.5 billion at the time. A few days following the coin burn the LUNA token hit a new record high. 

The burn aimed to remove value from Terra’s community pool, but in reality, it simply moved the value from the pool to the individual holders of the cryptocurrency.

Bitcoin Cash and Stellar are two other high profile cryptocurrencies that have made use of the coin burning initiative. Shiba Inu is another cryptocurrency to have undergone a coin burn, although this wasn't the initial intention of the project. The project's developers gifted half of the SHIB supply to Ethereum creator Vitalik Buterin, who went on to donate 10% and burn the remaining 90%.

How Does Coin Burning Work?

Should a project wish to implement a coin burn they will need to create a smart contract. Smart contracts are digital agreements that execute when certain criteria have been met. Say a project wants to implement a coin burn every 200,000 blocks, they will create the burn function to include this instruction.

When this milestone is achieved, the coins will automatically move from the designated wallet to a wallet address that does not have a private key. Without a private key, these coins can never be recovered. The coins will then be sent from the one wallet address to the other and effectively be removed from circulation. The transaction (burn) will be added to the network's blockchain records and be available to view through the blockchain explorer.

The Downside To Coin Burning

Before you invest in a project that undergoes coin burning it is important to note that coin burning does not guarantee an increase in the coin's price. The increase in price will depend on the network, the market climate and the current sentiment. During the Shiba Inu coin burn, while the price rose considerably, it soon returned to a more stable and substantially lower level.

Coin burning can also be used by ill acting developers to deceive the community. Say a project has a total supply of 100 million tokens and allocates 10 million to the platform's developers. They could then burn 40 million tokens, increasing their hold to 60% of the circulating supply on the network.

As with all transactions conducted on the blockchain, all payments are irreversible meaning that once you burn coins they can never be recovered.

What Is Proof Of Burn?

Not to be confused with coin burning, Proof of Burn (PoB) is a consensus mechanism similar to Proof of Work and Proof of Stake. The model utilizes an element of coin burning in its mining practice and is known to use considerably less energy than its PoW counterpart.

The process requires miners to burn tokens in order to participate in the mining process. The more coins burned the more blocks they can create, meaning the more rewards (in the form of transaction fees) they can earn. Miners are still required to use mining hardware. The benefit of this is to provide a less energy-intensive blockchain network that can run optimally through a network of decentralized mining participants.
