It’s not adjusted to “compensate”, it’s adjusted because otherwise they won’t sell any units. It’s based on time it takes to mine back your initial outlay for the cost of the miner. Plain and simple. Bottom line is, Bitmain makes the best profit in mining the units when there is fat meat on the bone. When they have sucked all that gravy from the networks, they turn and sell them to us so we can happily pick up their crumbs and leftovers. For some of thats OK. You just have to be careful of what you buy and how much you pay. I haven’t bought a Bitmain miner since December because you could see this shitstorm brewing. Well...if you were paying attention you could.
