I have a very new state of the art ryzen 9 3900x cpu.
I use it to mine at nicehash it auto converts all earnings to btc.
This pc earns 55 cents a day in btc.
So if I had 20 of them I would earn 11 dollars a day or 77 dollars a week.
This cpu costs 500 usd. If I worked at a low cost build with it. It could be built for about 850.

the two high-lited in rectangle are a ryzen 9 3900x and a threadripper 1920x they do from 1300 to 2400 hash on nicehash and earn around 85 cents a day
they convert all coin to btc so it is under 7 dollars a week add in the gpus it is about 17 usd in btc each week. not counting your power
those rigs = $$$ it would take more then 2300 to build them
