I understand what you are saying but two days ago the diff was slightly over 200K, now its almost double.
Everyday the block reward only increases by around ~0.288 ZEC. So block reward increases by ~6% while difficulty increases by 100%.
Its an effect of miner optimization, not so much reward yet. We will see hash-rate/price/diff equilibrium is about 2 weeks.
Sorry for all the questions I'm brand new to this whole thing, does that mean we should have a pretty good idea where zec will stand in about 2 weeks?
