You have to face the facts
i'm still not convinced that
bitcoin can get away with the same things any alt can. i hope we don't have to find out
But by which means can it not?
See, you can't talk in abstract terms here, there should be a mechanism which would prevent "the same things" from happening to Bitcoin. Obviously, it all comes down to individual people making up a certain community. So, are the people involved in Bitcoin somehow different (or, rather, conceptually different) from the people involved in alts? I'm strongly inclined to think that these are the same people mostly. What's more, I'd rather say that it is basically the same type of people which are involved in any cryptocoin out there barring some individuals like franky, who is going to stick to the "regular" Bitcoin no matter what (well, at least, so he says), but which are still few and far in between, and thus completely inconsequential
