It's sad for the account holders to not get the full benefit of the potential value in their account if FTX hadn't collapsed But it's still a massive win to be made whole in dollars versus the alternative of a big haircut. I agree that some of that capital is bound to flow back into crypto markets.
For comparison a family member worked for Lehman Brothers back in the day for a short period of time and he still got a few cents and dollars of unpaid wages over 10 years on from the collapse. He's not owed a huge amount but it's strange to issue cheques for pointless amounts. More expensive to pay the postage. Being made whole and being able to move on without it dragging on forever is a better solution
