#Bitcoin as a digital form of money, like virtual coins. It's not physical, but exists only in computers. People can use these digital coins to buy things online or exchange them with others. What's unique about Bitcoin is that it's decentralized, which means no single company or government controls it. Instead, a technology called "blockchain" keeps track of all transactions, making them secure and transparent. There's a limited amount of Bitcoin that can ever be created 21Million in total, which makes it valuable to some people. #nostr
