1. We need to simply stop buying the miners. We as miners should by only a few batches and then stop. If we don't do this the difficulty will become so high only people with huge mining operations will be able to show a profit.
2. Absolutely do not under any circumstance mine using their Ant pool server as this allows them to keep profiting from the sale of the miners and it forms a monopoly of profit for them.
We must mine some where else. Anywhere else otherwise Bitmain will completly monopolize and control all the coin markets. Part two is the most important.
Not to rain on your parade but those 2 suggestions are highly unlikely to happen. The first being more absurd than the second. History has shown time and again that some people are driven by greed. There will always be that someone who will want to get ahead of the rest and buy that miner or point their rigs to antpool.
I guess the only way for us to fight back against bitmain right now is to support its competition.
