So i noticed something odd..

The pool hash rate for bitcoin.cz has dramatically increased over the past few days, since the price dropped by almost 30% the pool mining hash rate has increased buy over 3 ph/s which i found about odd.

I then check this https://blockchain.info/charts/hash-rate and saw the the whole network hashing rate has infact sharply increased over the past few days, despite the price falling...

i though that was weird since as bitcoin price drops, so does mining profitability, and a drop in price by 30% is not a small one.

Any ideas?
