Don't forget the two Cryptonote coins, both with market caps over 1M$
Bytecoin
http://bytecoin.org/Monero
http://www.monero.cc/Monero has an especially high hash rate. Both are ideally suited to CPU mining although GPU is possible on Radeon and Nvidia. Neither seem to be dominated by bot-farmers. I mainly see AWS jumping in and out - fair enough in my view.
There are still coins easier to mine. I wish I could mine XMR with CPU and worth it, but I cannot. Still, sometimes I buy it, maybe it will have better days.
