I prefer pools with fixed high difficulty, the more you solve shares on a pool with high difficulty the better the end result will be for you, I suggest you keep using Viabtc pool and judge it after 24hrs of mining, then you will understand what I meant
Yes i agree reward chance gets higher but if you have high speed like 200-400mhs. but if he has 30mhs speed only pplns may ran very long for him.
Lol I'd just stick with Nicehash if 30MH is all I have, I think PPLNS pools are best for those who runs miners 24/7 none stop, that's why I don't use them, I prefer PPS pools because you can jump in anytime and exist any time too, you get paid for every shares you solve, things don't work like that on PPLNS
