i compiled a short list of what would happen if:
miners would be delivered end of Setember and the difficulty will continue to rise 25% every 11 days (re-target time)
good work thanks :-)
Obviously I hope that the difficulty will not maintain the current growth rate, wishful thinking probably.
In any case, if we have our rigs in time we will draw a good profit notwithstanding the growth steepness
My bet is that this does not stay linear. Nothing ever does. The only way that this would continue to grow at the same rate is if more powerful mining machines continue to be released. I don't see that happening in that short amount of time, therefore I expect the diff to plateau a bit. Probably rendering the more common GH/s units, either the 5GH/s or the 50GH/s units, into the profit realm of 5 to 10 dollars per day just like what is the case with the HD7970 GPUs today. There will definitely be a saturation point where people choose not to run their units because they don't make a profit.
