Just what appears to attempt to mining consolidated projects ends up causing this disillusionment with PoW, but have you ever thought of speculative mining? If you have interesting mining capacity and a nice cost of electricity so you can practice it, you'll probably do great deals if you're clever. I did a speculative mining with Bridgecoin in 2017 and the result was insane. I had problems with other coins too. 
Yes, I do not think that mining is profitable today, large projects continue to do this because 5% is a profit and no one will stop but small farms have already died. Or you are a giant or do not mine.
And if I'm wrong, then where is your profit brother
