> As long as governments begin to accept Bitcoin
Governments of small countries, maybe... but Bitcoin is already banned in China.
There are talks about a ban in Russia (Putin seems to be satisfied with taxing mining more harshly, though):

It's not a case that it was first China, and now Russia (which is in the top 3 for mining).
In the top 3 for mining there's also Kazakhstan, and their recent crisis was also caused by energy prices, so I can see them tolerating bitcoin only in the short term.
That leaves the US, but that country is too corrupt... And it has too many bitcoin billionaires to allow the value of bitcoin to tank. But no one knows how long this will all last.
As long as governments begin to accept Bitcoin, it becomes trivial to accept altcoins because they're often easily exchanged for Bitcoin.
