Yeah, the majority will be selling the coins immediately thinking they learned a lesson before. Some have all their saving on it too. There is still a small group of people who won't sell, mainly the true crypto enthusiasts.
The crash from December when the price was at $20k is not related to MtGox by the way...
Regardless, additional supply in the market will keep a lot of bears happy..
Mtgox wasnt entirely responsible for the $20k crash but it definitely help cause it. as they were market selling a lot on exchanges instead of going otc.
