Basically I want to know 110% relative to what? Say block rewards for bitcoin is 12.5. Then? He pay 13.75. How did he get the 1.25 BTC?
I think it is safe to say that if the block reward is 12.5 BTC he is paying 13.75. With regard to the 1.25 BTC I would imagine that some of the 1.25 BTC comes from mining fees in the blocks that the pool mines. But I believe that the bulk of the 1.25 btc comes out of Roger's pocket. At least that would seem to be the case based on a few emails we have exchanged.
