Please everyone here losses money not just in the current dip. The main question is how are you going to face it, you just sold everything and take the losses or just waited it out since bitcoin has a track record to recover?
Right now it looks like the dip is over because we have been seeing gains in the last couple of days. So if you just decided to push the sell button during the crisis, then you make the wrong decision. But if you did hold, then more patience is needed and wait till bitcoin fully recover and reach all-time-high.
For the reasons, its all over the forum, social media and other crypto websites. Government regulation is one, then FUD's by those people from behind who wants to pull the price so that they can bought it at a discount. That's how the market works since day 1, so don't be surprise but be prepared.
