Exactly which cryptocurrency is actually feasible to GPU mine? Bitcoin hasn't been feasible to GPU mine for years.

[Taek]

Many of them. Pretty much nothing sha based, and nothing Scrypt based, nothing stake based, but most everything else is fine.

Ethereum, Monero, Zcash, Sia off the top of my head, I am pretty confident there are at least a few dozen others as well.

Not feasible if you have to foot the bill. But if you don't...

Yeah, this seems like a scam that would be easy to automate too, for just about any rewards-based mining cryptocurrency.

Check out whattomine or coinwarz for a list.

There are a number of currencies specifically designed to be gpu mineable, in an effort to be more "democratic".
