Hi bro if you want best of best Bitcoin mining Rig than Bitmain antminer S19 pro that is the best if best and it offers 110 TH mining power and that can generate almost 6 to 7 dollars per day that is a good start and can be a best passive income. And there are many other coins that can also generate good profit too.
I just don't know if this calculation is correct if I base it on the S19 miner, please correct me if there is something wrong with what I am showing.
If you're gonna take a look at it, the profit in a month would be around 182.35$ based on 0.1KW
I don't know in 1000KW in a month.
0.1 is the price of your kw/h, not the amount of electricity that a S19 will use.
If a remember well a S19's electrical consumption is around 3.2 kw/h
