@Optikopti. I am not a miner but I reckon Aeon is more efficiently mined using CPU because of its cryptonight lite algorithm. For your question, post it in /r/Aeon on Reddit. Hihoguy will be more than happy to help you over there. He is one of the biggest miners in the Aeon community.
Thanks for the answer. i already posted that question there. hope he may see it
