Exactly.
Mining is more than 4 times more profitable than last year or beginning of this year.
And when the difficulty quadruples, if the ETH stays at this price, we will still be making more money than before

And, well, its gonna take a while to quadruple.

No need to panic, enjoy mining 

And if the time comes when its unprofitable, just shut down the rigs and wait for a few months or a year till the pump show starts again

Same like the miners with 79x0 and R9 series did
