The term “cryptocurrencies” describes digital currencies that are based on a blockchain. They are decentralised and can be exchanged without dependence on third parties. Cryptocurrencies have existed since 2009, the best known among them being Bitcoin. Although they have been around for a few years and have gained a lot of popularity in recent years, they are a relatively new form of economy, payment system and still rarely used.

They are based on decentralisation and the use of blockchains to verify and validate transactions. For many private individuals, cryptocurrencies are still completely uncharted territory and opaque. However, there are already many companies and organisations that express great interest in the topic or are already firmly working with cryptocurrencies.
