I feel like people are completely missing the point of Zcoin when they say things like you just did, basically: "MTP is all that matters for Zcoin"
That's completely untrue. I get that it has been marketed heavily as 'revolutionizing mining' etc, and sure, if it can fulfill its promises of putting CPUs and GPUs on comparable if not equal footing
I'll repeat myself: MTP heavily favors GPU. (Not that it's a problem, I think a PoW should favor GPU to avoid botnets mining.)
