I don't think that they will hold these bitcoins or are willing to hold them.
i actually do agree with you, i mean if i were one of the investor and wait for this long period of time I'm gonna sell little bit to enjoy profit they made a thousand percent if they sell right now.
Why would these claimants not have sold their claims over the past year+ to companies like Fortress, and then sell now when price is down by 70%? They were being offering up to $48K per coin back in March 2021, so not sure why they would hodl only to sell around $20K. Some claimants are dumb, for sure, but not most of them I don't think. As you pointed out, most would sell for profit, so likely already done so.
I agree many would have sold their coins already, that much is true. I don't expect most are hodling any more personally. What the new owners (mainly instiutions) do with these coins is another story though...
For some reasons maybe they are been hype again when seeing the price of bitcoin having a good run especially when it reach to its new ATH. Maybe they think that the offer of fortress is little bit low compare to the money they can possibly get if the price pump up for more.
Pretty sure that there are creditors regret their decision not to sell especially seeing the current price of bitcoin which is far away from its last ATH.
