I'm curious if anyone are still using these things and if they work and how much they currently generate per day as I'm looking to get myself one for a passive income.
Based on current values, you could earn a little more than a dollar a day (assuming nominal electricity costs). It's costs and earnings would need to remain at that rate for three to four years before you earned enough to offset the initial cost. However, the earnings seem to be trending downward and it's more likely you'd never earn back your initial investment.
