without a doubt, i'm sure some people got in to flip on ebay... just watch, they will show up on ebay.
With the current FPGA ROI vs anounced one i would be surprised if they do not appear on ebay.( I have already seen one for 70000usd) I am having second thoughts myself regarding fpgas because of uncertainty with roi. Despite it being considered the future of mining etc.
The market has dropped a lot since the FPGA hype started. Right now those that bought at $3350 USD are looking at making around $16-$17 per day, meaning a 200-day ROI; less if you use immersion cooling which drops the ROI down to 170-ish days. However I still believe the bitcoin ETF will create a huge upswing in the fall.
