re: mining contracts
1. look here
https://btc.com/2. You will see sha256 is very concentrated.
3. Genesis is likely odd man out, and hence screwing over their clients.
4. The odd feature; if Genesis allows, specifically still is allows for dedicated mining of the MM coins pools (UNO, SYS, NAME) ... okay ... but I personally do not know.
5. If Genesis fails on that level, there is little chance of them finding a niche in the BTC ecosystem ... next step is mining on retired hardware.

6. i agree, if genesis can't handle, then next door to the Peoples republic of NK is China, again back to pools that have2nd gen tech.
Kim .. if he is smart will buy out the tech.
