Mining the coins with CPU is no longer profitable guys. But with CPU you could mine many coins such as monero, zcash, litecoin, ethereum, dash, infinity coin, fantom coin and much more. Some of these coins can even be mined over your phone!! However as we know everything depends on the hash rates and solution per seconds given by your CPU. Today's difficulty is so much that even with i7 cores you can mine with 20 sol/s and 25 H/s rates which is just not sufficient enough to copup with the today's mining rate. You can do it for the fun anyway.
