The biggest issue with crypto as a currency is that there is no real way to revert transactions. That pretty much guarantees it will never be adopted as a currency. And forking the whole thing is not a solution.

There are a ton of other issues as well but those are more solvable.

So, no, with the current tech, I don't think it's happening and even if someone comes up with better tech it may be too tainted by scammers and finance bros.
