Communities can create value. The Bitcoin community believes Bitcoin has value, so it does. It has unique tokenomics with a limited 21m supply and is backed by math and cryptography. That's all there is to understand. Look into the history of money. Crypto just allows communities to have value. Soon you will see many communities online creating governance tokens, something like "reddit coins" but better, and you will be able to sell them for another coin like DAI or USDC.
