These people will become practical now. I believe there will be some people that will sell all Bitcoins will get because for sure they have some personal reasons or views with Bitcoin, but they are not at loss anymore.
But I believe there are still some people that may be sold some portion and they will hold some portion too.
We all know that's what will happen, their are some people that won't even sell any of their bitcon, am sure some of them will still continue trading even after losing their money during the hack, so some of them will still believe in bitcon am sure those once won't sell, but some of them that lose interest after losing their money in the hack will definitely sell now. But since they are already in good profit I believe the percentage of the once that will sell will definitely be high because the are already in good profit so they won't really want to hold it, which will slightly affect bitcoin price but we all know bitcoin price will bounce back.
