We heard the story a thousand times, Jihan Wu (Bitmain) is "gready" "a selfish miner" and so forth. No company has the guts to fully challenge Bitmain in the ASIC Miner business. Butterfly Labs and Halong Mining just couldn't break the monopoly.
As you may remember there was a big fiasco with Butterfly Labs sticking it to their customers. They were later shut down by the FTC (Federal Trade Commission):
As for Halong Mining, haven't heard much. They were out of stock a few months back.
There is enough big money BTC guys who could make a ASIC Mining company to challenge Bitmain. What are you guys waiting for? Yes, this is your signal go make that company.
Do something or put up with Bitmain. Blockstream can't complain if they refuse to act on the mining cartels.
We a quite a ways off from Quantum Computer mining. Win the ASIC turf wars before moving up.
