Be prepared to mine and not sell until the time is right. That may be a year from now, or it could be five years from now. Be prepared to mine until those gpu's and dead, pay for the electricity out of your own pocket ... And still hold your coins until the time is right.
Totally agree. Only started mining ETH end of last year. Then the difficulty spiked up drastically. Now have to fork out money every month for the electricity. Will continue until all the GPUs die.
What else to mine when ETH is going POS?
I don't think XMR will be that good, there is a market but if everyone who use to mine ETH will move to mining XMR you'll all flock in a pool. There are newer coins though like EINC which if it can have a good price, its going to set miners to build more rigs. I have it thinking as well when I saw their thread here.
