Not necessarily. We are reaching a point where the wider cryptocurrency ecosystem is beginning to diverge from Bitcoin. This statement would be more applicable last year. If Bitcoin was to completely crash right now I believe that it would negatively impact the price of other coins to a severe degree. Yet this would be temporary, and we would likely see a migration to another standard as the top coin positions itself into Bitcoins place. There are plenty of alternatives albeit most of them suffer from the same issues or even more than Bitcoin. Thus I find this scenario highly unlikely but possible. I truly believe Bitcoin will evolve to a meet the challenges presented. The fact of the matter is that cryptos are in the public mind like never before, and they are not going away.
