That's fine.
But what about the other things generated?
I believe these things might include toxic waste water, toxic air, and noise pollution.
The thing I linked to would simply replace the heating coil in otherwise typical water heating tanks. No reason to expect "toxic waste water, toxic air, and noise pollution."
The concept is quite simple: bitcoin mining generates heat (do it in server farms and you have to find ways to dissipate all that heat), you also need heat to heat your water. So just do the bitcoin mining in your hot water tank so the heat generated from bitcoin mining is used to heat your water (as oppose to dissipated into the environment as done by most server farms today).
