I will put it extremely simple for you. The gold rush is over. No longer will AM be able to make shitloads from selling shovels because there is already a massive surplus of shovels. Now it will come down to the most efficient large scale mining operations.

The only reason AM made so much money was the gold rush, a massive influx of people thinking they would be getting rich by buying hardware that they thought would reach ROI in 15 days. This scenario will never happen again.
