My two cents for what they are worth.
I believe in Satoshis original vision 1 CPU, 1 vote. The egality of CPU mining is that almost everyone can do it, even the poor, who are most in need of crypto to escape their economic situation and to secure it.
CPU mining may not be a popular approach however it would allow anyone with a cellphone to mine Zcoin, provided that a mining app is created. Almost everyone has a cellphone, therefore those interested in mining, could do it on their device, not just on a computer as not everyone has one of those.
CPU mining would level the playing field for mining, no pools would be necessary as everyone can do it, it would reorg the entire space and make it much more attractive to people, imo.
Heck, i would love to mine Zcoin but joining a pool, using my computer connected 24/7 then having to constantly upgrade my GPU so i can get a few percent of a ZCoin is just not attractive. But if i could run on my phone in the background that would be easy. Another benefit is that it would create extra nodes and increase blockchain security.
My vote is for CPU mining only, no GPU, no ASICS. Keep it simple, keep it in the hands of the everyday person, keep it on your computer and on your phone. Zcoin should never become elitist and only for tech geeks.
