Somewhat OT as well, but there's a bit of EE in here. I'm seeing a lot of bitcoin mining rigs for sale, which strikes me as odd. Basically, it's a box that generates money (sort of) when you plug it in. Bitcoin mining is very unlike selling gear for physical mining, where you also need claim rights, physical labor, etc. If I have a box that makes money when I plug it in (profit over and above the cost of the box and energy to run it) then why would I sell the box? Immediate return vs deferred maybe, but something doesn't add up here.
