Well, that sucks. While GPU mining is great for those who have high-end graphic cards, it's not suitable for the average person. CPU mining is much more accessible to anyone around the world, resulting beneficial towards the decentralization of any cryptocurrency. Upon researching different PoW coins, I've concluded that only two mining algorithms are easily mined with CPUs than GPUs or even ASICS. Such algorithms are M7M and yescrypt.
Magi uses the M7M algorithm for mining, which it's extremely easy to mine with any CPU. On the other hand, we've got Cryply (CRP) which uses yescrypt and it's highly accessible by average CPUs. The most interesting one is Magi, since it has a mechanism that lowers the block reward the higher the hashrate on its blockchain network. Additional security against 51% attacks is implemented, via the use of PoS. With Magi's unique algorithm, big miners cannot join the network resulting in greater decentralization by giving the power back to the small miners or the average person.
Nonetheless, I believe that the hottest CPU-only coins to mine right now would be Magi, Cryply, and Hodlcoin. Just my thoughts
I could be wrong, but last time i checked. If you won virtually every Hodlcoin block each day, i think you struggle to make $1 a day, and Magi is in a right mess. No leadership, multiple forks, pools up and down like yoyo's. Most original Magi miners left last year, and now a few bigger miners have it it, again, virtually impossible to hit $1 a day.
Prob best to stick with cryply.
