How cryptocurrency works
Cryptographic currency, better known as cryptocurrency , can be translated as encrypted money. We all know the traditional currencies such as the pound and the euro, but what we have seen in recent years is that we see rapid developments on the internet to overcome the disadvantages of traditional currencies. Cryptocurrency can therefore be seen as ‘internet money’. We all know the most famous cryptocurrency : Bitcoin. To explain exactly how cryptocurrency, such as bitcoin, works, we also need some knowledge of the technology behind crypto. The innovation of most crypto coins lies mainly in the decentralized nature (there is no central manager or issuer) and the fact that there are no ‘traditional’ institutions, such as banks, acting as intermediaries. Cryptocurrencies are direct, ‘money’ can be transferred without the intervention of third parties. Transactions are therefore faster and cheaper. But how exactly does cryptocurrency work ?

Blockchain
The operation of cryptocurrency works on the basis of the blockchain. But what does this look like in practice? To do this, it is important to understand somewhat how the underlying technology works: via blockchain. This is in fact a large database in which every transaction is stored. In contrast to a database of large tech companies, blockchain is not a central database that is in one place. Blockchain means that it is updated and copied by every user, so this happens continuously. This results in millions of ‘databases’, which makes blockchain very safe from fraud. Hackers who try to change transactions can only do this in one place, while there are millions of other copies in circulation. The blockchain databases are also constantly synchronized, so that suspicious changes can be detected immediately. This in combination with the rock-solid mathematical cryptographic encryption (hence the name cryptocurrency) makes blockchain safe from fraud.
This has led many people to expect blockchain to be a revolutionary technology that can be used for many other things besides online currency. Since it is still in its infancy, we must first wait and see how it will develop.
How much are cryptocurrencies worth?
Let’s talk about cryptocurrency again, currently the most relevant application of blockchain technology. Compared to the somewhat old-fashioned banking system, which seems to have little added value for many of us in recent years (unfortunately, you hardly get any interest on your savings), the world of all crypto coins seems incredibly exciting and interesting. But many will wonder: what exactly is a crypto coin, such as the bitcoin, worth? It all seems very abstract. A bitcoin is in fact nothing more than a line of code in the blockchain, what value can you attach to that? In contrast, you can say what normal money is actually worth, it remains only a piece of paper or a number in the bank’s database. But how does cryptocurrency work with regard to what it is worth? Very simple: money is worth what people believe it is worth, the same goes for crypto coins.
This also explains why bitcoin is so valuable. Bitcoin is scarce. There are a total of 21 million bitcoins, of which about 17 million are already in circulation. In addition, people believe in bitcoin as an alternative to traditional currencies and as a solid means of payment. The price of bitcoin is, just like that of other currencies, not constant. It fluctuates. Because it is such a new technology, it fluctuates even more than most currencies, which in the financial world is also called a higher volatility . This means that bitcoin sometimes shows enormous price peaks and troughs. So it still needs some time to earn the full trust of the people.
Crypto in use
Bitcoin has been increasingly accepted as a valid means of payment in recent years. This also applies to many other cryptocurrencies . In more and more countries you can make payments with crypto. There are even ATMs in some Asian countries where you can exchange bitcoin for cash. Bitcoin is also increasingly accepted as a means of payment in the Netherlands, mainly online. For example, you can easily have a pizza delivered with bitcoin. This currently costs a very small number of bitcoins. When bitcoin was just released, on the other hand, the very first transaction was 7 years ago when a gentleman bought 2 pizzas for about 10,000 bitcoins. Unfortunately for the gentleman, this would have been a fortune in 2020, if only he had been patient…
How do you store cryptocurrency?
How do you actually complete a transaction and store your crypto coins? It’s actually very simple. You need a wallet. As the name suggests, this is nothing more than a digital wallet or account. Because crypto is decentralized, there is no authority that manages your wallet. So you are responsible for your wallet yourself!
Storing cryptocurrency is an important point of attention. Some people have a considerable wealth of cryptocurrency. You want to store this well and safely.
Wallets
The question remains, how do you get a wallet? There are three different ways to do this. First, you can create a wallet through online exchanges that offer wallets as a service.
This is very easy to do, however it has a big disadvantage; you are no longer independent. Your wallet is on an external platform. If hackers can crack the platform, or if the people behind the platform have bad intentions, you can easily lose all your coins in one go.
The second option is to store your wallet on your computer. For this you need a wallet software. You are no longer dependent on an external platform, but there are a few things you should try to pay attention to. For example, you will have to make backups yourself and make sure that your computer is well protected against viruses and ransomware, so that no one can steal your wallet.
The third and safest option is to store your wallet on external hardware. Your wallet is then stored on a separate device and safe from hackers.
Speculating on the price of crypto
There is another option: instead of actually buying the crypto coins, you can also choose to speculate on these products. This way, you can use a CFD on crypto to play on the crypto, without the problems surrounding the storage of the cryptocurrency.
Anonymity
It is often said that bitcoin is anonymous, this is not entirely true. Transactions are publicly visible; everything can be followed exactly, from which wallet it was sent, when the transaction took place and which wallet was the recipient. However, the owners of the wallets are anonymous, no personal data is required to create wallets. Cryptocurrencies are indeed anonymous to some extent, but every transaction you perform with them can be traced by everyone.

Alternative coins
So far, this blog has mainly discussed bitcoin, the largest, oldest and best-known crypto coin. In addition to bitcoin, there are about 1000 (!) other coins. These ‘altcoins’, as they are also called, are all other coins. Well-known examples are Litecoin, Ethereum and Ripple. New coins are being added at a rapid pace. These coins often look a lot like bitcoin, but they often have one thing that makes them just a little bit different. Because it is such a young market, the survival chances of many of these altcoins are still very uncertain. When investors have confidence in it, this offers a little more future perspective, but at the moment much remains based on speculation.
The Future of Cryptocurrency
Bitcoin and some altcoins are developing very fast. Their use is increasingly embraced and the underlying technology offers many opportunities for the future. However, it is still questionable how governments and banks will position themselves towards cryptocurrency in the future. In short, the future still seems somewhat uncertain, but we are not done with cryptocurrency for the time being.
