If people support cryptocurrencies I dont believe that bitcoin will die. Goverments do not want to support cryptocurrencies because they want their own fiat money to be better. If we support and use bitcoin in real life it will never die.
Well, governments certainly can make it hard for people to have access to crypto though. They're afraid of something they don't have complete control on and they have the means to affect the crypro marker. Much like what's going on today. But not enough to make crypto cease basically.
