I have a few alts I'd send in should they accept more than BTC.
You could always use shapeshift or exchange them to BTC.
Not making the milestones of course makes me think what happens with the btcs? I mean lets say the coin goes live and first milestones are reached.
Devs get 50% of the ICO funds, but now something happens after the coin has had a little pump and many original ICO investors sold, probably at profit.
But 50% needs refunding to ICO investors, who gets the refund because the guys can go back and buy their original coins cheaper and get a refund?
I could be missing something and lets hope they want the remainding btc and it never comes to that.
If there is a refund, everyone gets a refund. If the coin goes live upon reaching the minimum milestone (>50 BTC), the project will continue.
But what happens if it fails or the devs go silent after they got some of the money, will the rest be refunded equally?
