Its good if they have something like that feature since its no sense at all if majority of them will unload immediately their bitcoin since it possibly could move the price of bitcoin plus provably these news will create a lot more panic since lots of people easily get carried out by the news they read online and some may think that this is risky situation that's why there might be a lot of people will join to dump their bitcoin.
I don't know the legitimacy of that news because I have heard it from another forum member. He said that the distributed funds will have a lock period, and they won't be able to dump it all right after they receive it. I agree that it makes sense because We saw how the market moves when many people dump their Bitcoin simultaneously. The German Bitcoin affected the market very hard and touched its lowest of 54K. If Mt. Gox users receive their funds without any lock period and they can sell all their Bitcoins, you will see that Bitcoin will touch 30K range or even lower. But I hope that won't happen. We expecting something good.
This is the article that fully explains the lock-in period. It varies based on the exchange claimants are going to use
The timeline for creditors to receive bitcoin or bitcoin cash repayments varies depending on custodians.
It may take up to 90 days for those claiming the repayments with Kraken accounts.
Mt Gox creditors may have to wait for up to three months to receive their bitcoinThis is to protect the market's impact in case the majority of them choose to sell their shares.
With the locking period, the market is safe from panic.
