#ALEO The 300m Mining Rig has been in my hands for less than a month, and it's almost turning into scrap metal. After the 720, in another month or two, when the 1.4g Mining Rig is released, the chances of recouping investment for the 720 Mining Rig are basically gone. Currently, even recouping investment for the 300 Mining Rig is impossible. Don't buy this Mining Rig unless you're willing to throw money at trial and error.
