What are cryptocurrencies and what are they used for?


Cryptocurrencies are digital forms of money that use cryptography to ensure secure transactions and control the formation of new entities. They operate in a decentralized manner, meaning they are not controlled by a government or central authority. Instead, cryptocurrencies use blockchain technology, which is a public, distributed ledger of all transactions made with that cryptocurrency.

Bitcoin was the first cryptocurrency to be introduced in 2009, and since then thousands more have emerged, each with their own specific properties and applications. Cryptocurrencies are used for a variety of purposes including investing, trading, and online financial transactions.

Main features:

  • Decentralized: You are not dependent on a central financial institution.
  • Immutable: Transactions recorded on the blockchain cannot be changed.
  • Secure: Cryptography protects transactions and user data.
  • Pseudonyms: Users are not identified via their real name, but via a wallet address.
  • Cross-border: They allow you to send and receive money anywhere in the world without high commissions.
