I barely make 8$ per rig now.
Do you think that miners will ever see the 15-20$+ mark or is that time period over?
What you're asking is if the price will recover back towards $20,000 before mining difficulty gets out of hand. I think that this is very realistically a possibility. If we pop up over $12,000 then we'll probably feel a bull market domino effect and quickly be up over $20,000. What you need to remember is that all you need to do is hold onto your coin until the prices go back up. That $8 can easily become $15-$20, all it needs is a little bit of time and patience.
