I ordered 2x AntMiner S7 that costed me a whooping 13 BTC + VAT and now with the big price increase, the difficulty will sky rocket because people paid only 4 BTC for a S7 and I'm pretty sure I will not be able to make almost anything back with my S7 investment, therefore I was thinking of trying my luck and solo mine on ckpool with my 2x S7.
What do you guys think ?
The chances of finding a block with that hashrate is extremely low.
I would suggest selling off your AntMiner S7's while they still have value and hold on the coins. That way you will make more bitcoins than mining.
