That unit's selling for $12,000.00. There is a Global Micro Chip shortage. That ROI is now 24 months at .04 per Kwh. There will be a lot of used ones for sale within 6 months as all the stupid COLO's and leveraged Mega farms that paid $120.00 per TH, go belly up because they can't service their debt. We've all seen this movie before. Good riddance to them all.
