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
The moment you get those "cheap graphic cards" is the moment you will pay to mine and nobody will want them. There is no profit in the bear market, trust me, you pay to mine.
