This is the last before halving if Im correct. This could mean last difficulty increase in a while as I expect many people shutting off mining when block rewards going from 25 BTC to 12.5 BTC.
I think we're going to see a huge increase before we start to see any decrease. New gen machines are just hitting the market, they are still very cost effective after the halving. I don't think we're going to see diff drop off a cliff like we speculated may happen. I'm gonna hold off on guessing a bit, see where we're headed. Looks like the peak is climbing back up again.
