Yep, absolutely no reason everybody shouldn't be merge mining. There's nothing to lose!
It's NOT split hashrate, if you mine XMR at 500H/s, and if you merged mined you would continue to mine XMR at 500H/s as well as MCN at 500H/s, at the same time, without using additional power.
It's soooo GREEN!
Is the term GREEN COIN a new thing or it was invented at the same time with the merged mining?
