If you have Bitcoin and think about selling, do not sell it cheap. We have been through major crashes, attacks, attempts at banning and he is still resilient and getting stronger.
Why not? if I don't use Bitcoin (as a currency) on a regular basis then i'll be forced to back and use fiat. A lot of investors will sell their Bitcoin even if the price is cheap as long as they're making profit. Blaming everyone for these short term dips doesn't help anyone. You should know that there will be people who are willing to sell Bitcoin because not everyone who's involved here has the plan of holding them for a long time. If several investors are affected because of these bad news then let them do what they want because Bitcoin will rise up eventually.
What you say is very reasonable. They only consider bitcoin as a means to make a profit rather than looking at its future value. When the price goes down or the market is not good they will be the first to sell it at any price to recover capital or a portion of the capital.
If you are merely an investor then you have to think about the price in the short term.
