I am aware of two cryptocurrencies I can get coins from for crunching Rosetta@home tasks:

Gridcoin (GRC) and Biblepay (BBP)

With Combined 30k RAC I make about $35-40/month from BiblePay coins

BiblePay recently removed their Team requirement,
so you do not have to join "Team BiblePay" to get their coins

Are there any other cryptos that reward for Rosetta@home tasks?

I've gotten some SPARC for crunching Rosetta@Home:

I have no idea if I can sell the ERC20 (Ethereum) token anywhere nor if it has any value.

I pay $0.13 kW/h (California USA) and I'm afraid whatever I earn in "crypto" is not breaking even at all. So, it is mostly a labor of love and "crypto" is most a nice thing to have.

Long-term, I think ARM computers or smartphones seems most energy efficient per RAC. I can run an old Android ARM quad core 1.2Ghz for 2.5w with the screen off. I forget what I get in RAC (its not much), but it also doesn't cost much in electricity.

Yeah, I'm running a LG V30 that gets almost 5000 credit and uses less than 5 watts. Can't get any better than that!
