I think that in order for Bitcoin to die it is necessary to make a big coup or just to create some very magic coin. But so far I dont believe in it and believe that Bitcoin is immortal or will exist as long as there are cryptocurrencies
In my memory:
2014 - an expert from the Federal Reserve Bank says that Bitcoin will die soon and will cost about $ 10.
2015 - Forbes compared Bitcoin with a dot-com bubble. They promised that by the end of 2016, Bitcoin will die and will cost about $ 1.
Then Bitcoin killer coins began to appear. You understand who eventually died. and then I just stopped paying attention to the next Bitcoin funeral.
