If you notice there are spikes about half way through every round then it settles at a certain point. I wonder why this is? Anyways Bitmain will have to come down in price since the release date is 2+ diff increases away.
someone figured out that he will make more btc if he turns off his big mine for 2~3 days.
those 2~3 days offline are a good trade off, because the difficulty for the next two week should be somewhat lower.
That myth has been debunked by simple math. Regardless of what pool payment method (PPS, PPLNS, etc) it is never feasible to hold back hashing power to earn more - unless you're 100% of the hashrate.
yes, I was referring to ASIC producers that are solo mining and selling devices to the general public.
