Probably true, if bitcoin would disappear, it will be slowly, and not drastic, it could only happen fast if governments would ban it, but, if ever no government involvement in its disappearance, I think bitcoin will always be remember each time we use new altcoins..
Yeah i agree if government banned bitcoin it will slowly disseapear beacuse the user and investors will worried about their money and sell it. And hoping that time will never happen but once gone theirs another replacement to that many will find another alternative for their self and find their ways to earn.
