well zergpool is even worse, i only got 0.31 zcoins after 29 hours of mining, while average pool hashrate was quite high (14-16mh/sec), i will reset payment threshold and try f2pool today with PSS payment system, i'm testing f2pool chinese server now with 2.2.1 build, well on f2pool it is more or less same as nicehash mtp, they pay you once in 24 hour, threshold is 0.1 zcoin, but with pss they pay you according your pool hashrate and not after each block found but immediately, just need 1 day to wait, no luck involved, only pool average hashrate and network difficulty matters
