Looking at the rapid growth the Croptocurrency world is experiencing right now, with new and promising Tokens (ONL, ATFS, BERRY etc) being introduced on regarly basis. I actually have a strong confidence that cryptocurrencies would get worldwide acceptance in the nearest future, and with Bitcoins topping the charts of all existing Bitcoins right now, Bitcoins stands to benefit from the newborn cryptos emerging. So if you ask me, I think it is quite impossible for Bitcoin to CRASH.
I have come to learn that anything and everything in this market has a possibility to happen, therefore, I think that even if it could be the worst thing that could happen, I always leave a space to think for a contingency plan if that really happens. However, for now, cryptocurrency, though it may seem that it has been there for a long time already, is still in its baby stages, and so, it still has a long way to go. I say that because the market still has a lot of thing to improve on and a lot of changes to undergo, so even if it might crash, that would not be anytime in the near future.
