I'm not saying the idea of cryptocurrency is dead, but I'm certain that if a crypto will in fact make it to widespread adoption, it will not be Bitcoin. Bitcoin has several horrible flaws.
Name the flaws, I dont see any.
Your dreamer if you think some altcoin magically take over Bitcoin. Most devs working on Bitcoin software, and the software is so reliable only because of them. If not Bitcoin, no decentralized cryptocurrency will succeed
