Those that are ASIC resistant but not GPU resistant, such as Curecoin, Foldingcoin, and a number of other cryptocurrencies.
Curecoin has a component that is ASIC mined, for blockchain security - the rest of it IS NOT A CRYPTOCURRENCY at all, the rest of it is a reward for doing Folding@Home work.
Foldingcoin is not a cryptocurrency at all.
Bad examples there.
Better examples would be Ethereum, ZCash, DGB, and such that actually ARE cryptocurrencies.
