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 think maybe I'm scared that bitcoin will crashed someday but the important is now that we earn as long bitcoin is there. Like some saying not all in this earth be long forever. But I think someday many things will be change in crypto so earn as you can as long bitcoin is there.
