With BTC at $286 right now - UMISOO is paying an estimated 0.74155560972143600% daily... 
Very nice, but how much power is UMISOO...? I can only seem to buy it on the market under Hash
I'm not sure I understand your question. Yes, UMISOO is available from HashNest. Choose the menu item "hash", then "UMISOO", then "market" to find the buying menu.
"Power" would be 0.67478569276522800% daily at present...
Sorry for the confusion. A hopefully better way of expressing it would be: How many GHS does UMISOO has, given that it can be bought as an unit (as we can buy an S5).
