The fall is due to the bitcoin's fall, a possible transition to lira2v(z), or something else? There are any versions.
I think MTP is XZC's next target algo. It should have been implemented a long time ago, but I heard they ran into some problems. It's fine though, because I like lyra2z, really power efficient.
By the way, zcoin lyra2z mining became quite profitable for CPU mining, was getting around 1 usd on a i7 -7700k
Switched my cpu miners from cryptonight to lyra2z for a while
Oh nice. What clocks is your 7700k running at? What hashrate do you get?
