Bitcoin is money that operates based on consensus, all participants in the network voluntarily follow the same rules encoded in the software. It doesn’t rely on leaders, companies, or politics. The rules are the same for everyone and cannot be changed unilaterally. That’s why Bitcoin is often compared to the game of chess.

In chess, everyone knows the rules, how pawns move, what castling means, what checkmate is. These rules are immutable , and that’s exactly why the game makes sense. If someone decides their knight can move like a queen, it’s no longer chess. Similarly, if someone tries to change Bitcoin’s fundamental rules, they’re not changing Bitcoin ,they’re creating something else.This is the essence of hard forks. When a group tries to change the rules (for example, increasing the block size), they can create a new chain , like Bitcoin Cash. Technically, this is a new game, played by new rules. That’s why it’s no longer Bitcoin.That’s why such forks quickly lose value and eventually go to zero, because people don’t trust them and don’t accept them as the real Bitcoin.
