The cost of a kwh here in FL is 11 cents. So that would mean 66% profit, 34% electricity cost. And if you have solar, you're golden! And after the mining rig has paid for itself, you still have thousands worth of GPU cards. And this is with Bitcoin being priced at 33000 dollars, can you imagine if it went up to 300k?!! This is a life changing money making opportunity with minimal risk that so many are passing up including me.
Knowing my luck, that's exactly what would happen if I bought a rig. I guess it's only $2.5k and you could still use it as a heater.
Yes because all I would have to do is shut the mining rig off after I sold everything. While still having thousands worth of mining equipment to mine other tokens. Easy peesy man!
Any heating savings you made during the winter would be offset by additional cooling costs during the summer. So there isn't really a net gain unless you live in a climate that stays cold year round.
If you run it alone (no one other than big miner factories do that) then if/when you hit one, you get (currently) 6.25 BTC. If you don't (and when you are running one miner it is very unlikely you will) you get nothing. Most people with less than let's say 2000 miners join a pool. In a pool, when someone in the pool hits, everyone in the pool gets paid proportional to the amount of work they put in during that period.
Integrating a refrigerator and a miner makes sense lol. We'll rate them in MH/s/BTU or something like that.
