You are wrong :v. If you dont have to spent money on electricity then its profitable for you :p prove me wrong. People cant make profit because they have to spent huge money every month on electricity
I don’t have to provide you an example calculation, that has already been done. Even when electricity is not free, as long as it’s in the single digit cent range and you got the miner as close to MSRP as possible, it will work out.
I have no idea how people buy miners
at MSRP, but if you could get an S19 for 2500$, esp. if you got it at launch time (as early as possible due to difficulty ever increasing), it would have repaid in a few short months.
