It also gave all of us the "idea" of something like "Bitcoin", a form of "money" that is not controlled by the state, is achievable.
Bitcoin might fail, but the idea lives on to make a better "Bitcoin".
Bitcoin was first created to become the future currency, but what is happening now is that Bitcoin has changed its function, becoming a traded
commodity asset, so this is not a failure of Bitcoin, but a setback in digital currency technology, because if this happens then the function from bitcoin only as a digital asset, bitcoin should be returned to its original function as a payment tool, because bitcoin has the potential to become the world's single currency.
FTFY: a commodity is a raw material used to create products.. bitcoin is a asset currency.
