Learning the friendly way

Sitting among the 30 biggest cryptocurrencies by market cap, Stellar is focused on bridging the gap between the business of blockchain and the traditional financial institutions. The platform provides a means for users to send assets and money through the blockchain, utilising a decentralised network of authenticators.

Redefining the financial landscape, Steller presents a digital transformation on the traditional services users have become accustomed to. Merging innovation with a practical application, the network is able to help users around the world, as well as financial industries, achieve a more streamlined service. Let's explore what Stellar is.

What is Stellar (XLM)?

Before we dive into the "what", let's first stipulate that one stellar is known as a lumen and uses the ticker XLM. Stellar launched in July 2014 and soon afterwards changed its strategy to be more focused on integrating blockchain technology into financial institutions. 

The concept behind Stellar is to provide a space in which users can transfer everything from traditional crypto and fiat currencies to tokens representing new and existing assets, increasing their transaction performance by using lumens.

Similar to the Ripple XRP network, Stellar is designed to cater to both payment providers and financial institutions, building a bridge between the blockchain and traditional financial sector. Developing on the Ripple concept, Stellar has also positioned itself as an exchange as its ledger has an inbuilt order book that keeps track of all the assets on the network. 

Who Created Stellar?

The founders of Stellar are Jed McCaleb and Joyce Kim, both previously employees at Ripple. McCaleb, who founded and was acting CTO of Ripple, and lawyer Joyce Kim, decided to create Stellar after they left the Ripple team in 2013 following a disagreement on the direction that Ripple was taking. McCaleb is also credited with creating the first successful Bitcoin exchange, Mt Gox. 

McCaleb described Stellar's aim as giving people a means of moving their fiat into crypto and more seamlessly conducting international payments. The network provides cross border transactions with low transaction fees and fast executions. With leading technology and innovative problem solving, the network has made a healthy impression on both institutions and investors alike.

How Does Stellar Work?

Stellar is a hard fork off of the Ripple network with several similarities in design and functionality, however, the platform set itself apart by building in several key features. The platform is secured through the Stellar Consensus Protocol which revolves around these core business concepts: decentralised control, flexible trust, low latency, and asymptotic security.

The biggest upgrade launch came in 2015 when the platform replaced its consensus mechanism with a concept called federated Byzantine agreement. This required nodes to vote on transactions until quorums are reached. Anyone is able to join the consensus, and there are measures in place to inhibit bad actors operating with ill intent on the network.

The software behind the platform is called Stellar Core and can be altered to adhere to the needs of the operation using it. The nodes making up the network can be created to function as either Watchers, Archivers, Basic Validators or Full Validators. For example, watchers can only submit transactions while Full Validators can vote on which transactions are valid and maintain a ledger of all node activity.

Another element to the network is the Stellar Anchors. These gateways are responsible for accepting deposits of currencies and assets and issuing depictions of these on Stellar.

What Is XLM?

Known as lumens, XLM is the native cryptocurrency to the Stellar platform. XLM acts as an intermediary currency for transactions taking place on the network. With cost-effective experience priorities, every transaction on the Stellar network costs 0.00001 XLM, a fraction of a dollar (at the time of writing). 

When the platform launched in 2014, 100 billion lumens were minted, programmed to increase by 1% annually until the total supply reached 105 billion. Five years later the Stellar uses voted to end this process. 

That same year, in 2019, the Stellar Development Foundation (a non-profit organisation) reduced its share of XLM in order to regulate the Stellar economy. This brought the total supply down to 50 billion. At the time of writing, roughly 49% of this total supply is in circulation.

Risk management involves identifying and analysing the risks involved, and then choosing whether to accept this risk or make changes to avoid the risk. This process is one we carry out daily, from crossing the street to engaging with a stranger, however, in this realm we’re looking at it from a finance/investment point of view. 

If you have a fund manager or financial adviser, they will generally be responsible for calculating and communicating the risks associated with any type of investment. This will cover the potential returns as well as the potential risks to your capital. 

For example, investing in an emerging asset will hold a lot more risk than buying the stocks of a well-established institution. It’s worth noting that high risk doesn’t necessarily equate to a negative, typically assets with higher levels of risk bring about higher levels of return (high risk, high reward).

Each person’s level of risk will vary from one to another and should be decided prior to making any investments. Once this is established, your investment portfolio will work within those realms so as to manage that level of risk.

While the crypto industry continues to grow at a breathtaking pace, one problem continues to run wild. That problem is the fact that blockchains are not interoperable, meaning that they can only exist in their individual nature. Polkadot set out to change this, creating a network that aims to connect multiple blockchains in one simple solution. As a direct competitor to Ethereum, the blockchain network has a different structural approach.

What Is Polkadot (DOT)?

Polkadot is a blockchain network created by one of the Ethereum founders. Through the use of intricate architecture, the platform aims to connect multiple networks through their relay chain and parachain system (more on this below). 

Similar to Ethereum, developers can create their own decentralized apps (dapps) and smart contracts on the network. Referred to as a sharding multichain network, Polkadot aims to provide a platform on which developers can build multiple blockchain networks off a common standard. Traders can then trade a range of products built on the network, similar to how ERC-20 tokens are traded.

Who Created Polkadot?

Founded in 2016, Polkadot was created by one of the Ethereum co-founders, Gavin Wood, alongside Peter Czaban and Robert Habermeier. Woods notably created the Ethereum language Solidity, which allows developers to create dapps on the Ethereum network. 

Wood is also the founder of Parity Technologies and the president of Web3 Foundation. Web3 Foundation is a Swiss foundation that was designed to facilitate a user-friendly, open-source decentralized web. The company's approach to crypto is one of its kind and sets it above any other competitor.

How Does Polkadot Work?

As mentioned above, Polkadot utilizes a relay chain and parachain system. Each parachain is a blockchain in itself, however, they all rely on the relay chain to facilitate transactions. These blockchains work in a "parallel" manner (hence the name) and can each hold their own tokens and individual use cases. The relay chain provides blockchain support to the parachains on the network.

Finalizing the transactions and being responsible for maintaining network security, the relay chain is able to facilitate 1,000 transactions per second (TPS). Utilizing a hybrid consensus mechanism, the enterprise network has created proof-of-stake (PoS) and a nominated-proof-of-stake (NPoS) model. 

Through this variation, anyone can stake DOT in a particular smart contract and perform network roles such as being a :

• Validators (validate data in parachain blocks, vote on network changes)
• Nominators (select validators by delegating their staked DOT to them)
• Collators (nodes with full histories of each parachain, that transfer this information into blocks for the relay chain)
• Fishermen (responsible for monitoring the network and reporting bad behaviour to the validators)

These four roles allow Polkadot to have a highly sophisticated user-driven governance system as each role contributes to maintaining and securing the network while eradicating bad behaviour. 

The network is working on a third blockchain functionality known as a bridge. Bridges will allow blockchains on the Polkadot network to interact with "outside" blockchains, essentially allowing tokens to be swapped directly without needing to go through an exchange. 

Through this intensive structuring, Polkadot aims to solve two problems that the blockchain network is currently plagued with scalability and governance. 

What Is DOT?

DOT is the native cryptocurrency to the Polkadot network and is used as a governance and utility token, allowing users to vote on proposed upgrades and used for gas fees. It plays an integral role in maintaining and operating the network. As a digital currency, it can also be used to execute cross-border transactions.

The platform was launched in 2020 and has already established itself in the top 10 biggest cryptocurrencies. 

Does Polkadot Have A Max Supply Cap?

To answer the question "what is the total supply of Polkadot" the answer is that there isn't one. The network opted to leave the total number of DOT infinite. At the time of writing the circulating supply was just short of 1 billion coins.

What Is The Difference Between Polkadot And Ethereum?

A common question in the crypto community, not just because they share similar use cases but also because the two networks share a founder. Both networks provide a platform on which developers can create their own blockchains, and following the launch of Ethereum 2.0., will both be using a PoS consensus. 

Structurally the Polkadot platform differs in that it makes use of parachains and a relay chain. This is a unique feat in the blockchain industry. Through this structure, the network aims to improve on several of Ethereum's functionalities and deliver a trifactor of governance, scalability and interoperability to the blockchain industry, without compromising security. 

How Can I Buy Polkadot?

If you're looking to incorporate Polkadot (DOT) in your cryptocurrency portfolio, look no further than Tap Global. A recent addition to the exchange's portfolio, users can buy, sell, trade and store DOT directly through the professional app. Whether looking to trade DOT for its technology and smart contract capabilities, or to tap into a new market, Tap allows traders to diversify their cryptocurrency portfolio in one secure location.

We have all heard older generations complain about the price of products "nowadays", talking about how $1 used to buy them a movie ticket and popcorn, compared to the average cost of $10 for just a ticket today. They aren't complaining about nothing, this is a very real issue the world is currently facing and it's known as inflation.

Although, with the way the economy has been going lately, hyperinflation may feel like a more fitting term. In basic terms, hyperinflation is referring to a very high and accelerating inflation rate. Let's cover what inflation is, and how this differs from hyperinflation.

What is inflation?

Inflation refers to a decrease in purchasing power related to a specific currency. This means a progressive increase in the price of goods and services results in a certain amount of money being able to buy less over time.

As already stated above, what $1 used to buy back in the day is merely a fraction of what the product or service now costs. Usually, inflation occurs at a gradual rate, however, there have been instances where inflation rates have accelerated at much faster speeds. This rapid acceleration rate leads to the value of a country's currency being diminished at an alarming rate. This is then referred to as hyperinflation.

Hyperinflation is measured when the inflation rate increases by 50% or more in one month.

What causes hyperinflation?

You may be wondering how hyperinflation occurs, and that's a great question. From an economic standpoint, there are two main causes, although external factors can also come into play. External factors might include war, natural disasters, a pandemic, and more, however, here we will be covering the two main causes.

Number one is an increased money supply. Most think that an excess supply of money sounds great, but it can have colossal impacts on a currency if not backed by economic growth. Countries usually grow through trading, businesses, and bringing money into the country from outside the borders.

This issue comes into play when countries print money at an accelerated rate, increasing government debt with central banks which they then have to pay back with interest. This additional interest and debt gets placed on citizens, who are then expected to pay more tax and pay more for products. 

The second is demand-pull inflation. This can also be described as supply vs demand. While some small businesses see this as a benefit, being able to increase prices due to their unique products, the same can not be said for common household items. This inflation occurs when the demand for products goes up, especially as capitalism rises, yet the production of said products can not contend. 

This creates a gap within the supply, making it hard for businesses and economies to make money unless they raise their prices. So again, we see product prices rising thus reducing the purchasing power of a currency. 

The effects of hyperinflation 

One of the most common effects of hyperinflation is the devaluation of currencies, moving those who hold them to switch to more valuable assets. Whether it is investing in the stock market or another currency, this takes additional money out of the currencies' economy and proceeds to make hyperinflation worse. Luckily those who have invested in other means of value are not as affected by this additional pressure.

Previously, inflation in Zimbabwe reached such dire levels that the country ultimately wrote off its national currency and switched over to the US dollar. At one point, their currency was so hyperinflated that their $100 trillion Zimbabwe dollar banknote could only buy a few loaves of bread. This impact affected banks, foreign trading, and basic government services, creating another ripple effect leading to further inflation. It's a problem that continues to occur, ravaging countries and livelihoods around the world.

Hyperinflation and monetary policies

Central banks play a vital role in preventing hyperinflation through the implementation of monetary policies.. As they control the money supply, regulate interest rates, and oversee the stability of the currency, central banks are responsible for maintaining a balance between growth and inflation. Done so by carefully monitoring economic indicators to manage and prevent potential risks of excessive growth and inflation.

In order to keep hyperinflation at bay, governments need to practise responsible fiscal policies, avoiding excessive borrowing and uncontrolled spending. Maintaining a stable exchange rate and encouraging foreign investments can also strengthen economic stability.

How to combat hyperinflation

In an attempt to curb the devastating effects of hyperinflation, below are four measures that governments and central banks could implement.

Tightening money supply

An obvious one, central banks can reduce hyperinflation risks by curbing the rapid increase in the money supply. This involves limiting the printing of new money and implementing stringent monetary policies.

Interest rate adjustments

By raising interest rates, central banks can discourage excessive borrowing and spending, which acts as a means of stabilising the currency's value and mitigating hyperinflationary pressures.

Currency controls

Implementing currency controls can be a smart move to stop money from leaving the country and prevent risky speculation, all while keeping the currency strong during uncertain economic times.

Currency reforms

In extreme cases, currency reforms, such as introducing a new, more stable currency or adopting a foreign currency as legal tender, can be considered to tackle hyperinflation and restore economic confidence, as was the case with Zimbabwe mentioned above.

Examples of hyperinflation in history

These instances from the past where hyperinflation wreaked havoc serve as a clear indication of the devastating economic impact it can have on countries.

Germany (Weimar Republic):

During the early 1920s, Germany experienced one of the most infamous hyperinflation episodes. Printing money to cover war reparations led to the German Mark's catastrophic devaluation, resulting in absurd price increases and widespread economic collapse.

Zimbabwe:

Mentioned above, in the late 2000s, Zimbabwe endured a severe hyperinflationary crisis, reaching unimaginable levels. Rampant money printing and political instability eroded the Zimbabwean dollar's value, rendering it practically worthless and forcing the country to abandon its currency.

Venezuela:

Starting in the 2010s, Venezuela suffered a hyperinflationary spiral driven by a combination of political mismanagement, plummeting oil prices, and economic turmoil. This ongoing crisis has caused immense hardships for the Venezuelan population.

Yugoslavia:

In the 1990s, Yugoslavia grappled with hyperinflation as a result of political fragmentation and war. Spiralling prices led to the eventual replacement of the Yugoslav dinar with new currencies in several successor states.

Hungary:

Post-World War II, Hungary faced hyperinflation of unprecedented proportions. Skyrocketing prices and economic instability plagued the country until it eventually switched to a new currency.

These history lessons serve as cautionary tales, showing us just how terrible hyperinflation can be and why it's crucial to have solid monetary policies in place to protect against these economic disasters.

In conclusion

Hyperinflation, rapidly increasing inflation rates, is a serious economic problem with disastrous effects, as seen in historical examples like Germany, Zimbabwe, Venezuela, Yugoslavia, and Hungary. While central banks play a crucial role in preventing hyperinflation through monetary policies, governments must too play their part and practice responsible fiscal policies.

While inflation rates might feel dire, hyperinflation is highly unlikely to ever take effect in the United Kingdom as The Bank of England and government have many tools at their disposal to identify and prevent the onset.

Decentralized finance, or "DeFi," refers to financial services that provide many of the same features as traditional banks - like earning interest on your money and borrowing from others - but without middlemen who take a fee or charge interest, paperwork, or privacy trade-offs. A chartered accountant and Blockchain do not have much in common, but they are starting to as DeFi and FinTech take over. I

nstead of relying on financial services like banks, users can utilize smart contracts on blockchain. Cryptocurrencies ensuring even more ease of use for DeFi users, providing the hottest speeds, fees, and transparency. Defi and digital currencies are growing in popularity thanks to the perks of Blockchain technology. Let us get more into the concept and how it caters to a larger audience.

The aim and use of DeFi

Decentralized finance is the future of financial services, and it's already here. The aim of DeFi is to provide a decentralized financial services platform that is open and accessible to anyone in the world, using tech like crypto to help advance the everyday life of anyone and any business willing to give decentralization a try.

In the past decade, we've seen a rise in peer-to-peer lending platforms such as Lending Club, Patreon, BTCJam, and an explosion of digital currencies such as Bitcoin and Ethereum.

All of these developments have taken us one step closer to the decentralized future of finance that we've been dreaming about, but there's still more work to be done.

What's wrong and how can DeFi fix it

Many institutions in the financial sector are slow and expensive when it comes to providing basic services like payments. Online lender contracts can charge interest rates as high as 30 percent, and the global remittance industry charges fees that can be as high as 12 percent.

These fees and delays mean some of the most vulnerable individuals of our society are paying the highest prices for financial services when they need them most. While the traditional financial system can be slow and expensive, it doesn't have to be this way. Decentralized finance (DeFi) is an emerging category of services where trust intermediaries such as banks are replaced with cryptographic code and smart contracts, which reduces costs for everyone involved - especially when it comes to international payments.

DeFi is a new category of services that are globally accessible and built on top of blockchain infrastructure, without any charge or barrier to entry. It's also much more secure than traditional financial systems because the technology used isn't connected to a central server that can be hacked. DeFi users smart contracts applications to ensure ease of use and instant transfers of information and funds.

Your money is always yours; it's just moving from one smart contract to another. No permission from an intermediary is required in order to use it. All you need to do is have a cryptocurrency wallet, computer or mobile device, and internet connection like everyone else using DeFi services today.

DeFi isn't coming, it's already here

When you ask yourself, "where is DeFi going?", the answer is simple: everywhere. DeFi can be used from every corner of the world, and it's already available today. Innovation at its finest.

DeFi services are not theoretical. They're already being used by real people today to make real asset payments, earn interest on their digital savings, and borrow money from both friends and strangers, all without ever going through a bank or traditional financial institution. Whether you are investing, a money maker, or an asset holder, the shift to DeFi is inevitable.
Blockchain technology provides the first-ever opportunity for these separate building blocks to come together in order for the entire financial system to work seamlessly without any intermediaries, so it will only get better with time. From an economic standpoint, DeFi offers better rates and all the perks of FinTech. Cryptocurrency assets like Ethereum have seen plenty of investment opportunities arise as DeFi and Blockchain merge.

DeFi pros and cons

In order to get a complete picture of what DeFi is, it's important to understand all the good and bad parts that we are facing now. So let's dive into the details.

DeFi pros:

• The interest rate on savings and money lending is relatively high, just as it would be without intermediaries.
• Financial services are more accessible than in traditional bank systems because there aren't any barriers to entry, like non-existent internet infrastructure or bank account fees.
• Transaction and disruption times are much faster because DeFi transactions can move directly from peer to peer without having to go through intermediaries.

DeFi Cons:

• Some transactions might not be as private due to the public records of smart contracts on a blockchain (keeping that in mind, transparency is always beneficial). This however increases security because fraud or reversal can't happen.
• Access to DeFi services can be limited if you live in a part of the globe where these services aren't supported or don't have high enough adoption rates, as compared to traditional banking systems in developed countries. Regulator issues may also occur.
• There isn't a built-in mechanism for handling consumer disputes between peers because the technology simply wasn't designed with this function in mind.
• It's difficult to understand what you're getting yourself into when joining a DeFi service, since it varies from one application to the next and is based on new technology. This doesn't have to be the case in the future.
  

As of now, it's still the early days for DeFi and there are some challenges to overcome before we can look at it as a real alternative. There's still a lot of work to be done, but it will all pay off in the end.

Investing centers around making gains off of your initial capital. When determining the potential gains one could make there are a number of variables one needs to consider, such as how much capital one has put into the investment and what returns are associated with that asset class.

This led to the creation of ROI (return on investment), a measure that allows anyone to calculate the net profit or loss of an investment in percentage form. 

What is return on investment?

All investments, including stocks, bonds, real estate, and small businesses, come with the goal of making more money than you put in. The money you earn over and above your initial investment is called profit. When discussing investment profitability, people often use the term ROI, meaning return on investment. This metric expresses the amount of net profit one can earn/earned as a percentage of what the initial investment was.

ROI can help you assess if buying property or investing in a business is worth it. It's also helped companies determine the value of adding new products, building more facilities, acquiring other businesses, advertising campaigns, etc.

ROI (return on investment) is the percentage of gain or loss on an investment relative to the total cost of the investment.  In other terms, it's a way to compare different investments in order to figure out which ones are worth pursuing. For example, you could calculate ROI to decide whether selling one stock and buying another would be a good idea.

While there is no limit to a return on investment theoretically, in practice, no investment is guaranteed to have any return. If your ROI is negative, it means you not only failed to make a profit but also lost some of your original investment. The worst possible outcome would be -100% ROI, meaning you completely lost your initial investment. An ROI of 0% signifies that you at least recovered the money you put in, but gained nothing beyond that.

While ROI is often used as a marker of profitability, it isn't foolproof. There are several limitations to calculating ROI as your only measure which include the time frame in which you will earn back your investment, inflation rates, how risky a venture is, and additional maintenance costs that may be incurred.

Calculating ROI terminology

Before we dive in, let's first cover some basic terminology.

Net profit or net income

Net profit is the amount of money left over after all operating costs, such as the cost of transaction costs or maintenance costs, and other expenses have been accounted for and subtracted from the total revenue. It is used to measure profitability. Net profit can also be called net income, net earnings, or the bottom line.

Total cost of investment

This figure will look at the amount of money invested in a particular investment.

How to calculate ROI: the ROI formula

The ROI formula is a simple equation that looks at the price change of the asset and the net profits (the initial cost of the investment minus its value when you sell it). When calculating ROI you would use this formula:

ROI = (Net Profit / Total Cost of Investment) x 100

To factor trading costs into your ROI figure, you'll use: 

ROI = ((Value of Investment - Cost of Investment – Associated Costs) / Cost of Investment) x 100

As an example, let's say you buy 5 shares of $100 each in Twitter, equating to $500. You sell them a year later for $150 each, equating to $750. Let's say you paid $5 commission on each trade, costing you $25 in trading fees. 

ROI = (($750 - $500 - $25) / $500) x 100 = 45%

This means that you made a 45% return on investment on that particular investment.

How to determine a strong ROI

A "good" return on investment is any number above 0, as this means you made some profit. However, the ideal ROI should be higher than what you could've earned had you chosen another investment (the next best thing). 

To compare this, investors often compare their earnings to what they could've made on the broader stock market or in a high-yield savings account. Using the S&P 500 as a control, over the past four decades it has made gains of around 7% (after inflation). An ROI is generally considered to be a strong one if it beats the stock market in the long term. 

It's always important to note that past performance does not equate to future results. Another pearl of wisdom to remember is that high rewards generally come alongside high risks. If an investment promises very high ROIs, consider this also means that it comes with high risks. 

Therefore, a strong ROI will vary depending on the investment's level of risk, your goals, and how much risk you're willing to take.

Where the ROI formula falls short

The main limitation of using this return on investment ROI formula as a marker of success is that it doesn't show how long it took to earn the money back. When comparing various investments, the time it takes to mature will have a significant impact on the profits you could earn.

For instance, a year loan versus a bond held for five years versus a property held for 10 years will all have varying ROIs once you've established how long it will take to earn the specified ROIs. 

In this scenario, the ROI calculations mentioned above skimp on the full story. It also doesn't account for risk. For instance, the loan repayments could be delayed or the property market might be in a slump, all affecting the potential profits earnable.

With many variables, it becomes harder to predict what the exact ROI calculation on an investment will be, so be sure to factor this in when using the return on investment ROI formula to determine how attractive an investment opportunity or business venture is. 

ROI alternatives

Although the return on investment doesn't consider how long you keep an asset, it's essential to compare the ROI of investments held for comparable lengths of time as a more clear performance measure. If that's not possible, there are a few other options.

Average Annual Return

Also known as annualized return on investment, this adjusts the ROI formula to factor in the timing. Here you would divide the ROI by the number of years you hold the asset.

Compound Annual Growth Rate (CAGR)

This option is more complicated but yields more accurate results as it factors in compound interest generated over time. 

Internal Rate of Return (IRR)

This measure factors in the notion that profits earned earlier outway the same profits earned later, taking into account interest that could've been earned and factors like inflation. This equation is quite complicated but there are online calculators one can use. 

Conclusion

A return on investment (ROI) is a formula used to calculate the net profit or loss of an investment in percentage form. The ROI calculation can present valuable information when investing capital or determining profitability ratios. The ROI equation looks at the initial value of one investment and determines the financial return. A negative ROI indicates that the investment returns were lower than the investment cost.
