The difference was Spondoolies were selling at a horrific loss, which isn't good for anyone.
... except for your current benefactor, which killed Spondoolies off by undercutting them on price, and then started price-raping customers when they became the only game left in town, amirite ?
So you're saying its Bitmain's fault that Spondoolies got it wrong with the SP20 and chose to sell them off at a significant loss in order to generate cash?
