Maybe it's an IOU market? Not sure.
Also i asked a few questions, got this reply in about 12 hours for those with other questions:
Your choice of equipment also determines which mining pool you can use. The following three pools are available to Giga Watts clients: Slush Pool to mine bitcoins, NanoPool for Ethereum and LitecoinPool for LTC (we are working to integrate support for more pools coins as well). We do not believe ETH will go PoS that soon (if at all; there will be testing first to see if its viable). But yes! Giga Watt is currently working to add support for XMR, ZEC, and ECL. Your rewards will be distributed to your digital wallet multiple times daily. If the pool you are mining with does not solve a block then no rewards are distributed,.. but this is rare. You will still pay hosting should that ever happen but we expect rewards to outweigh costs. We are working to support more coins, but you will not have the ability to reprogram; however, if and when we do, Giga Watt will be able to make that switch for you.
