I can see in this chart that the dash mining difficulty doubled only during the last month.

And that's without these super powerful beasts in the market. So how possible it is the difficulty will follow this trend and by the time we get the A5 the difficulty will be 8x - 16x higher than now? Which would mean the profitability will be lower by the same multiple? Is that a viable scenario?
