Please don't troll this thread. Thinking that the difficulty will raise nonstop with 15% is simply unreal and it's bad intended. There are other threads where you can speculate about the difficulty, but this is not the place and i won't allow it.I will just add that considering that the SP30 will be the most efficient miner starting from August it means that you will be able to mine for a longer period of time than the whole 50000TH/s that is plugged in right now supporting the Bitcoin Network. I don't want to continue this discussion and i will delete all further posts about it. Take it to another thread!
