This is like saying Heartbleed is proof the Web will never work. You can't even guarantee secure connections! What will happen when the spy agencies start using these?! Decentralization isn't proof a system has no bugs, it's proof the system works without an authoritative governance, which I will remind you is the topic at hand in this particular comment section. Is crypto a scam? Maybe, maybe not. If you think so, just don't use it!
