Bitcoin was heavily marketed as a currency. It failed at this.
Bitcoin was heavily marketed as decentralized where no single entity owns 51% of the network. In fact Bitmain likely already does or soon will control 51% of the network [1].
The remarkable thing here is that despite these clear, observable failures... Bitcoin will go on. The true believers will continue to HODL and while shorts may pile on in the absence of fundamental economic data there's little reason to buy or sell. The price now is purely a popularity contest.
