For each coin that may be mined, this multicurrency mining pool has a minimum payout. It may interest you to know that I was able to gain access to this mining pool without having to register, and that you can conduct dual mining with a very cheap commission on this platform.
Pay Pay Last N Share is the technique used to disperse rewards. This means that the reward miners receive is proportional to the percentage of the overall share they contribute.
In my opinion, the cost is acceptable when compared to other mining pools, however if the pool's staff can lower it, they will still have an edge over other pools. It's important to remember that the charge changes from currency to coin, depending on which one you choose to mine. The charge is also affected by transaction GAS.
