Of course not, don't ever think about that. Cryptocurrency will never die, it will grow up as second payment after currency itself. Even China do that, there's many countries with different policy allow cryprocurrency to become their fund instrument. You only need to see big picture about crypto world and leave wrong mindset. I choose to invest & trade with crypto because I believe crypto still have future. But if you're not sure about crypto future, just leave it, no one will stop you. Have a nice day
