That's exactly what i mean.
People will donate/pay for profitable algo's. Kind of makes sense doesn't it?
If a farm with 1000 cards starts to mine with djm34's 25% faster neoscrypt kernal. The diff will skyrocket and the algo will not be profitable.
If they mine x11 with my 1% faster kernal, and the powercost is 90%.
The profit after electical bill will be 10% higher.
1% faster will not change the x11 difficulty.
