Both of these ways require picking a good service to store and manage the funds, which can be a little challenging for a beginner. In this article, we’ll review some basic rules on how to choose a great cryptocurrency exchange. However, before digging deeper into making money, let’s see how cryptocurrency works overall...
The concept of digital currency has existed for many years. Before cryptocurrencies, there were many attempts to create some form of digital money. One of them was Ecash, which was created in 1983, and it became Bitcoin’s predecessor. In 2009, Bitcoin was created by Satoshi Nakamoto, a mysterious developer, and the new class of assets was born.
Bitcoin was the first example of successful blockchain technology implementation in finance. A blockchain is a database where the entries are sequences of blocks. Every block contains information about the previous one, its hash, and of course, information on transactions. Blockchain is a distributed technology, in the case of Bitcoin and the majority of other blockchains, copies of the database are stored on the nodes of all participants. This distribution allows making sure that nobody would be able to change the database, to reverse transactions or to add new ones without everyone knowing.
Another feature is that every user has their own wallet – to send or receive cryptocurrency, you have to know a public key which is a sequence of Hex-numbers, for example, 1PAt5oKQGBRigFDY6fB2WgQTtQJNzFyTDr. The private key, on the other hand, is a tool that allows signing transactions and managing the funds. All the assets on blockchain truly belong to their owners. Overall, immutability and true ownership are two things that differ cryptocurrencies from the government-issued fiat money.
