most post-bubble bagholders would sell as soon as they can break even if they could to get out of this mess
That's actually one of the bigger issues of the near future.
That's not even a problem.
Let them sell. Others will buy.
I don't see a problem. People are selling Bitcoin every day.
People are buying Bitcoin every day.
People are dumping Bitcoins every day.
And it will be like this till the end of the Bitcoin/World.
