Tell me something you geniuses, what happens when someone finds an unlimited power source and then deploy 800,000 of the best miners available and starts mining without worrying about the energy costs? someone found a way to profit more than others by mining more efficiently and now you are asking why and are bu*t hurt? important thing is that they contributed the required computational power by the algorithm and besides the algorithm was there from the start publicly available unless bitmain developed the mining algorithm and implemented a back door in it? I don't think so. as always there will be hand above hands meaning there will always be someone smarter, accept the fact and move on because no crime were committed here.
Well, the only issue is that they are actively pushing against Segwit softfork due to the fact that it will mess up their AsicBoost and were wanting to hardfork instead.
