I believe bitcoin is the future. When all the fiat currencies are going down, I can see the bitcoin go up.
I think that bitcoin will continue to grow even when sometimes it takes a dip, it can take a hit and will bounce back up.
But what would be the reason for fiat currencies to fall down enough that Bitcoin is adopted? I can't think of a single reason why across the world fiat currencies would all fail. Some might fail due to internal country economic policy failure and economic downturn but it would have to something insanely radical to affect the whole world. A more likely idea is that Bitcoin and fiat co-exist for a prolonged period until Bitcoin is recognised to be a superior alternative and further infrastructure is built.
That could happen but perhaps in the future there will be a Bitcoins replacement in which it will be a perfect cryptocurrency with no block size issues, faster TPS and more. Unless, Bitcoin gets some improvements, then it will remain the most solid cryptocurrency in the world. Just my opinion.
