calling Bitcoin as fail project are obviously those people that stupidly invested in this market knowing only one thing , and that is a place where automatically making money so in the end, blaming crypto for their greediness.
You shouldn't waste your energies with those people kept on calling bitcoin as a failed project. There's nowhere to go with that argument and Bitcoin doesn't have to prove anything to them.
there is no such place like investing with exact making money.
if you don't know how to deal with the risk of cryptocurrency , then never invest here unless you have learn everything in right manner before putting your single cent here.
They're just looking for someone to blame for their mistakes and not acknowledging themselves to be at fault. We've known Bitcoin for how many years and it has given us the surprises that we'd liked and disliked but still manageable scenarios.
