Mainly depends upon your current heat source. Natural gas is 1/3 the cost per unit of heat compared to electric heat. Miners can cost a lot up front. Its a fun mental exercise, doesn't make SATs in most situations.

Ahh that's good info. I'm on natural gas. There's no way the bitcoin rewards I'm getting from an s9 is making up for that 1/3.
That said it's a bit of a labor of love so I'm ok with taking a bit of an L if that means I'm securing the network and earning non kyc sats.
