@Sebar25 Hello, the best profitable coin at this moment is definitely Catcoin
furthermore it's like Dogecoin in brief they're both funny and more !
But they both are scrypt based, so no reason to mine them on CPUs. For CPU Skeincoin was really good for last month. It use Skein algo. It wasn't available on exchanges, and there were only about 100 miner, so could have like 50% of coins with 100+ cores (you could just set you own price on market with such amount of coins). But now it has GPU miner as well
