What is decentralization and why is it important in the world of cryptocurrencies? Imagine that one day you and your friends want to exchange rare trading cards, but instead of doing it directly between you, you always have to go through an adult who checks, takes a percentage and decides whether the exchange is valid or not. This adult is a bank or a centralized system. Now, think instead of a system where you don't need an adult to check the exchanges. All your friends have an indestructible notebook where they write down each exchange, and everyone can see that the rules are respected. No one can cheat or change what is written. This notebook is the blockchain and the system that supports it is called decentralization. Why is it important in the world of cryptocurrencies? No boss, more security, more freedom. In practice, decentralization is like a large group of people who trust only the mathematical rules, and not a single boss. This is why cryptocurrencies like Bitcoin exist: they allow anyone to exchange value without having to go through a bank or a company that controls everything. #Fordummies #decentralization
