I was actually rebuilding my rigs back in June 2019 when the alt markets were rallying again and basically less than 1 month later the profits were shot down and been pretty bad since then. Would be nice if we could stay at least >$350 for the next few months or so. Because the difficulty obviously will keep rising and people will keep scouping up cheap RX gpus on Craigslist to mine and the difficulty will keep rising every day until the profits vanish.
If we get >$1000 ETH or ProgPOW then obviously the profits will be great once again however I am not sure we can reach that number. Hopefully we break the 2019 high for ETH this time around and head into the +$500 area for ETH and other alts like XMR.
Yup... we are in similar boats. My power is 11 cents so just recently got in the ballpark of an acceptable "profitability-to-effort" ratio. I also turned back on all my rigs last June... and also for just over a month lol... until prices dropped again. Really hoping for a sustained action this time. Not sure we will see ATH any time soon but if it could even fluctuate between $500-$600 for a while it would be well worth it.
As you point out, anything over $300 range will start to bring more and more people back into mining, which in turn bumps up the difficulty. I'm curious as to how many people like us actually help onto all/most of our gear through this 2nd downswing. Can't imagine there were that many but who knows. I almost started selling mine off multiple times but just never did it lol.
