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).
UMISOO are shares of AntS2 units. You can buy as little as 1 GH/s.
