Used across all markets, the spread is the difference between the buy (offer) and sell (bid) prices of an asset. Spreads provide an additional opportunity to traders to make money through buying and selling assets.

The spread of an asset will depend on the current demand or an asset and the market’s volatility and is presented in either a percentage or value form. Assets with markets displaying higher levels of demand will typically have smaller spreads and usually higher price points. 

As an example, when you look at an order book for Bitcoin you will usually see prices reflected in green and red reflecting the offer prices and bid prices. The spread will then be indicated above the most recent trades. As another example, consider foreign exchange counters where the buy and sell prices are different, this difference is known as the spread. Market makers use spreads to generate money from transactions completed at market prices.

Let's put this in context: George buys 100 shares for a £2 ask price in “ABC” a publicly listed company. George pays £200 in return for 100 shares. If he decides to sell the shares back at the same price he bought them for, he would sell the 100 shares for the bid price at £1.95 and would receive £1.95 each instead of £2. This would mean he gets a return of £195 and loses £5, which would be paid to the market maker.

Risk in trading is the chance that something might negatively impact an investment. Before engaging in any trading activities it is important to evaluate your appetite for risk, determining whether you are able to handle more risk or are more risk averse. 

Measuring risk will be dependent on the type of asset you are investing in, the amount of capital you have to use, and the time frames in which you expect to see results. Different assets and trading strategies hold different amounts of risk. 

For example, investing in an index fund is considered a low-risk investment and is better advised to investors looking to make a slow and steady return over a longer period of time. Index funds aggregate the performance of the 100 companies listed on a particular stock exchange and pay back dividends accordingly. Because they are large companies the growth is often more likely to be smaller yet consistent. 

With a little more appetite for risk, in the crypto markets, the same could be said about choosing to invest in an emerging altcoin versus established cryptocurrencies like Bitcoin or Ethereum. An emerging asset would encompass a higher risk higher reward ratio, however, no returns are guaranteed. 

You can speak to a financial advisor to get a sense of your risk appetite.

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.

Cryptography is the process of converting messages into unreadable text so that only the intended recipient will be able to read them. Cryptography is responsible for the security, anonymity, and trust less transactions of digital currency. – entirely without the services of a financial institution.

We'll define cryptography as the study of methods to exchange sensitive information over an insecure channel in such away that only authorized parties can access it. In our case, this will be exchanging ownership of cryptocurrencies (which is represented digitally), or transferring ownership by signing digital messages.

A bit of history:

Cryptography dates back to the time when people began exchanging messages in forms other than face-to-face conversations(e.g., via written letters). The first known use of cryptography can be traced to Egypt, about 2000 years ago, during the reign of Pharaoh Thutmose III. Other known historical uses of cryptography are in the works of Julius Caesar, who used a simple cipher for messages between him and his generals.

The purpose of cryptography in crypto

A blockchain-based cryptocurrency needs some form of encryption to secure its money supply from being stolen by hackers or malicious software. It also allows for the anonymous transfer of funds between individuals without requiring a trusted third party, such as a bank or government institution. Cryptocurrencies are entirely based on cryptographic ideas.

Compared to cash transfers, cryptocurrencies do have another layer of security built into the blockchain: cryptography. The purpose of which is to validate transactions and prevent unauthorized access to the ledger by keeping all information inside a digital file that only authorized people can see. It's kind of like a physical vault (or safe) where you can keep all your money. But, unlike a physical vault, there's also no way to access the safe without a private key or password.

Usage of cryptography in Cryptocurrency

Cryptography is used in several different components of Bitcoin's security model, as well as in other cryptocurrencies.

Bitcoin addresses, which are used to receive and send funds between people on the blockchain, have both public keys and private keys. Only the owner of an address's private key can spend funds sent to the address, and only the owner of an address's public key will be able to receive them.

Every time you send or receive bitcoins, your transaction is signed with the appropriate digital signature using your private key. Since you can't share your private key with the person receiving your bitcoins, they verify that the signature is correct using your public key. The process of sending and receiving bitcoins between addresses is entirely anonymous and doesn't require any personal information (although there are ways to link transactions to identities).

Cryptocurrencies use public-key cryptography in order to prove ownership of addresses and transactions. This is done with a piece of data known as a digital signature, which is obtained using the sender's private key, and attached to the end of every transaction block along with other information about that block. Each new transaction has its own signature, verifying that the sender owns the address that is being used to send the funds. Since only the owner of a private key can create a digital signature for it, this provides a very strong guarantee that nobody else has sent their cryptocurrency to an address other than the one currently being spent from.
