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
"That Pays Bitcoin" means that There are Signature Campaigns that PAYS in TOKEN ( their own token or coin ) which somehow other TOKEN ICOS that has this kind of signature campaign that pays via their own token or via stakes are SCAM, Sone ICOs with Signature campaign pays BTC or bitcoin and not via stake, With this kind of strep i said that the trust of the community will be gained. There are rare number of ICOs with signature campaigns that pays btc and not altcoins/stakes/token.
