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.
200 day ROI is still very good IMHO.
Also people should realize the low power usage for this return. My 24*1070ti eats (and heats) up 2600w/h
Two BCU will make more money than my whole setup for around 300w...
Power cost and use is key. The current state of the market favors miners with low power costs. If you have free power, then efficiency is less of a concern and you can buy up cheap, but power hungry mining gear. If you have more expensive power, you want more hash/watt efficient gear, and FPGAs deliver that.
Only in the crypto world is an ROI in under a year for equipment "too long."
