Etherium. "WINTER IS HERE". pos/pow state.

At this moment Etherium difficulty is skyrocketing.Big spike last hours almost 20% minus of mining revenue.

**The bomb is set and here are the results.From 1395 difficulty to 1655 in a few hours.

My prediction is that mining eth is not goin to be profitable by the end of year if it continues like this.(maby november pos/pow)**
what do u think about the trasition? will it be viable till pos/pow hubrid or they will go to a pos root immediately? and when? which month?
will it affect the price goin up?
