There’s a huge amount of gear going offline and coming online again. Most of the operations are relocating or selling massive amounts of gear to large entities, so I think the opportunity will be limited to miners getting a couple weeks of low difficult rewards.

With BTC prices having dropped nearly 50% so quickly, I’d personally rather be a seller than a buyer of anything priced in USD right now.

I also don’t think we’ve dabbled in used equipment before and with the rate of failure we’ve seen in new equipment, buying used stuff now seems like a risk as you’d likely get the stuff the big companies thought was in too bad of shape to sell to their large partners.
