I'd say it's like YiiMP considering it's an implementation of that opensource pool
https://github.com/tpruvot/yiimpIt's sort of like MiningPoolHub in function. What ever you mine will be auto-exchanged for BTC, or other listed coin by using "c=CoinSymbol" in the password field, so you kinda sell hashingpower by default, selling what you mine for BTC or other coin of your choice.
you can buy hashingpower with their "HashTap" thing, though sadly it seems new user registration is down atm due to some technical issues with their captcha of all things.
