Is it? The used data center P40s I bought for $150 2 years ago went back up to $450 a few months ago, I sold one for $400. I just checked and price is down to $200, so I'm still profitable. I bought MI50s for $90 less than a year ago, they are now going for $200. What deterioration? OPs gear was far less and is no longer deprecating. It will probably hold this value for the next 4 years.
