Mining Bitcoin from home has been a great experience. I'm not profitable with this old machine but I'm stacking sats every day. Even when I don't have fiat to buy more coins I know I'm making 900 SATs a day uninterrupted.

Cost me $108 for this Antminer s9 + $58 to replace a hashboard. Worth it to me.
