I second that. Mining is doomed because of Chinese manufacturers.
Before they sell you the equipment they are mining and raising the difficulty level.
I suggest to STOP buying Chinese equipment so the BTC price will go up instead of fall down.
This has been going on since the dawn of ASIC mining. Boycotting manufacturers won't stop them from producing hardware and mining with it.
Correct but the major manufacturers have already mentioned the US$200 limit. ie. if BTC hits or falls below that, it is the end for some manufactures. The manufacturing process costs more. Currently they are operating on very small margins. Don't be surprised to see one or two close or be sold to others who think they can turn them around. This was expected.
