I'm trying to save on oil and be able to consistently heat all winter without worrying about cost of fuel. And earn btc while I'm at it. I'm nervous but I think I will try this , this winter when I return to work. On paper I'm seeing I could see a net gain of $8,000 annually , including savings on oil. I have seen other people do this also. Going to be following your YouTube videos If you end up making some. Thanks for inspiring me!!
