No one is snapping up the S9s because difficulty has increased so much & is continuing to increase daily, that the S9s no longer mine much bitcoin in a year. In Nov. an S9 was mining about 1 bitcoin regardless of price. Fast forward 3 months and an S9 mines less than 0.5 bitcoin. Right now bitcoin is having a tough time breaking above $9000 and may end up going back below $8000. So paying $2320 for an S9 now is a big risk with so much going against bitcoin. Also, there are hundreds of S9s and huge lots being sold on eBay now vs. a month ago.
