UPDATE: on the legality of a home mining operation. Where I live you only have to REPORT the coins at “fair market price” when they hit your wallet. However, this is not a taxable event. And even then you only pay income taxes on 50% of your coins when you sell them (if you are not an industrial operation). Or you can never sell and borrow against them as they appreciate (like Manhattan’s real estate). So my comment stands, it makes no sense to bury newly earned money on a legacy system “Tax free savings account”. I checked a couple of other countries in America (the continent) and the taxable event is when you sell the coins. So, in most of America(the continent) is legal as long as you report it. But apparently this is not the case in the United States according to some people here.
