I voted for too many scams, let's speak the truth here, it is really hard to trust this ICOs ( which you can see that almost daily they are posting on altcoin announcement thread) I'll trust them if they can create a signature campaign that pays Bitcoin. With that step i think they will gain the trust from the investors.
sorry for the offtopic but first this:
What do you mean "that pays Bitcoin"?
and now on topic:
This is cool idea, I think the most big problem is that there are not easy accessible wallets for the altcoins, so you can have the private key.
This is the biggest problem for me, as I can not trust exchanges with my coins, and it is hard to make wallets for all the altcoins.
So this is the biggest problem for me. Also not small problem is the scam that comes with new alts...
But this idea is really cool and I hope you develop it good.
P.S.: IDK why but can not vote on the pool
