So if Dash fails (and I think it will stumble) then it's us and ETH (for now).
DASH is a sound success now. That means people will start investigating more about its background. We know what will happen next.
From what I've read ETH code is big and badly written, so it's all about when the next bug(s) or exploit(s) will pop out.
So the question is:
when will XMR reach 100$? It means just a little over 4x rise from this point!
