Oh, definitely. It has more time than most to fix it's problems, but if they don't get resolved then there could be a slow exodus to something else. I think the bulk of it's power comes from being it being the default trading pair. If that starts to dissolve, then it might be a turning point. For instance, with Coinbase starting to open up to other alts... People can easily go from fiat to something else without needing BTC as an intermediary.

Well, also a huge lead in hash power doesn't hurt either..
