Your argument is based on the statement that difficulty keeps rising. While historically this is true, it is not a guarantee of future patterns. Yes, we have seen some insane rises in difficulty, but that is due to a number of factors including wider acceptance, general knowledge of crypto-currencies, incredible hardware advances, etc. I don't think we can state as a fact that difficulty will forever continuously rise.
Just wondering... I thought that the difficulty levels where built in to the whole pattern... or design of bitcoin and mining...
I thought that it was set well in advance every level?
Is it possible that it will stop going up??
I figured for sure within a few months I would be pushed out because of this and the expenses...?
Running 4 TH for a few months now and it has gone way down.....
