Mining in flats is more of a hobby, most apartments dont even charge for heat so you are wasting a resource there. I guess one benefit is drying your cloths with the heat, and saving on your electric there?
home owned mining you can have a decent sized farm and and get alot of benifit from solar since residential rates are high most places. Also u can have a heat pump water heater tap off some of that heat and save power and also dry your clothes
You are talking about right things. But in fact it's very difficult to realize. Also payback of these technical solutions is too long espessially at current price levels of crypto.
Much more simpler to rent a rack in data center and don't worry about cooling, noise and safety
Yes if you can get a data center rack for a good price, That solution usually isgood for asics since they have low matinance, gpu rigs need too much babysitting imo.
I agree right now its a bad idea to do anything but crypto will go back up and at that time u might regret not investing in the future
