Because when this incident happened, the value of bitcoin was very low and many people were not even aware of bitcoin.If these people get their bitcoins back and those people sell bitcoin, the market can crash a lot.But it is also possible that they charge a price in against for these bitcoins But one thing to note is that people who were aware of the importance of bitcoin in 2014 will sell bitcoin in a bear market?.  They will wait for the Bull run.Therefore, it seems unlikely that the Bitcoin price will crash further
