...But if you want to stack coins with no kyc and have a need for heat a modded m50 or s19 is viable....
Even with the mods, unless you know something I don't, you still have to get 220V to wherever you want the heat.
I am using a modded S9 for heat in the back room of the condo at the moment, would love to do something faster / more efficient but it's all 120V without doing a bunch of work.
