The vast majority of the crypto world failed to understand one key concept, money is not the value for which goods/services are exchanged, it is the value by which they are exchanged. People do not have a use or value for money beyond what it can be exchanged for, if no one is willing to exchange for it, it has no value.

Crypto only had value as a currency if people would accept it for goods or services, and the only thing people ever accepted it as payment for, in any meaningful capacity, were illegal goods and services. The value beyond that was purely based on a speculative ideological assumption that people would abandon the traditional banking system for a new system that they couldn’t buy anything with.
