Forget about CPU mining coin. This type of coin usually shit-coin. And believe me, it will never grow if you only depend on the CPU to secure your coin's network.
Several coins can be mined with both CPU and GPU like Monero and other Cyryptonight based algorithm. But remember that you're also compete with GPU rigs, therefore your profit will be really small.
Why are you giving such bad advice when you clearly have no idea what you are talking about.
Many of us are making good money mining cpu only coins (yes some are even finally gpu mineable with minimum gains).
Simple fact is, that some of us spend days weeks, even months finding coins, so are unlikely to give away the crown jewels, at least not in public.
For the record, right at this moment in time i am making nearly double cpu mining over gpu mining, you've just got to look really hard.
