I don't we would be here if we didn't support Bitcoin. I believe that Bitcoin will never replace FIAT, but will rather find itself as a way to transfer funds anonymously when it simply isn't safe to do it otherwise, whether for good or for evil, much as it is now. Overall, I think Bitcoin will still be around 50+ years from now because simply put, there is no other cryptocurrency as stable and as big as Bitcoin-there's just no substitute, no matter how small its job is.
