Is there any plug and play crypto miner that doesn't make noise and doesn't generate heat like GPU and ASIC?
And it should be profitable, and it should be cheap, and ready to be delivered right?
There is no miner that actually does something without generating heat, the only solution is to get a miner that has water cooling. like the S9 hydro (which was not that popualr_ of the upcoming S19Hydro, which, of course, nobody knows how reliable it is.
Plug and play, no heat, no noise, ..no miner!
If there's some second hand, one of the ones I remember was the antrouter r4 but make sure you use escrow or something that can cover you.
The router was R1, the R4 was a "silent" miner but at 8TH/s per 900W, you're barely getting 1.8$ a day with no free electricity at 8 cents you're losing money, the router, it hashes in GH ranges
