So, In the past 2/3 weeks I have seen two miners (the S3 and S4) go into negative earnings and in or near redemption.
The S5 and S7 has increased by 20% in te past two weeks.
So, What will happen to hashnest if the difficulty continues to increase, or when te halving occurs? Will they ever consider using other equipment such as BitFury miners (when tey come out).
This has happened several times before. As the difficulty is increasing the hardware start to become obsolete and then is time to step into a new and more efficient hardware.
They must be preparing to launch new hardware to keep up to the dif increase and net growth. Besides, don't think they are not froseeing what will happen after the halving because they do.
