Mining profit is way down today, it would be stupid to ask way 
but my main concern is when will GPUs flooded the market again? 
I want some cheap graphic cards for long term mining, just added 4000 watts solar panel days ago, I want ravencoin rig, ergo and conflux rig separately
Profits still ok not bad, the answer for your question will be if eth price goes below 1.5k then you will start massive gpus for sale.and i think this time there will be more gpus than 2018-2019 bear market, nivida oversold old gpus even old 1660 and 2060 sold like hamburgers and also add to them old polaris gpus but my main concern is when will GPUs flooded the market again? I want some cheap graphic cards for long term mining, just added 4000 watts solar panel days ago, I want ravencoin rig, ergo and conflux rig separately 
, but do not think bad yet because BTC and ETH still holding its price.letsee what is coming this time.
