~ Many of those who plan to receive payment with Bitcoin are likely to store BTC rather than selling it when Bitcoin has decreased by more than 60%.
Yeah it dropped sharply but let's not forget that the Mt. Gox incident was like 2014 and the price back then was just around $500-$600 per bitcoin. The current price isn't going to be much of a factor because they are clearly still in a good place if they decide to sell once they got their share.
As to the effect on the market, it might cause another dive to $18K level (could be lower) but it will be absorbed like any other sell offs.
on the weigh of averages
the price at the MTGox close was in the $100-$1200 range for the couple years prior to close.. lets call it an even $400 for pencil math(not everyone bought at the same time)
imagine it was for easy pencil math.. 850k customers with 1btc each
well they aint all getting 1btc each back... they are getting (pencil math scenario) a 6th of their account balance
which is on average 0.16117647
which at todays price is still $3k
so still profit in the end. so selling is still profit
the only thing that matters is that its not a case where the coins are going to need to be sold by court order of settlement in one shot/one order to fulful a court ordered fiat amount settlement
by releasing the fund AS COINS. it atleast wont be a full 137k sell off in one shot. one sell order.
instead it can be sporadic and long term selling off chunks by old whales with more then a few coins.
though with all that said.
selling at the bottom of todays market is stupid.
they are in profit and some may just want out and forget about crypto there will be some sell off.
and some that may just hold
and now have fun speculating.. because no one knows what all the people will choose.
..
if i personally had coins in at the time. and a meaningful amount. i would have years ago wrote them off as a loss and forgot about them so it wont consume my life/stress levels.
then if getting a letter saying im getting a 6th of my balance mid summer. id choose to hoard. i wouldnt sell at this low market price even if they are in profit.
(but then again i actually do have my own hoard from 2012era, at super profit which i kept in my own private key where im not ready to sell)
though i do expect others to just want to sell up and move on if they totally removed themselves from crypto years ago
