For people who have a long-term investment strategy, sit nicely and watch a favorite movie is a good thing, let the price weaken and go back up. But if you have a short-term investment strategy and intend to see the bitcoin price movement selling bitcoin when it's downhill is the best solution! Hold your money and when the price is at the bottom and trend up price come you can buy back. I'm sure you will get a profit compared to HODL and let the price go back up.
I really do not even bother myself when situation like this arrives. Traders are happy making a living out of the fluctuation in the market, I am happy making a good living from my job with some additional passive income alongside of it, so I am not bothered where bitcoin heads to now, it is the future that matters and that is what I am all about. Anyone who wants to panic because of people like OP who make it a living to spread FUD, then that is their choice.
But one good thing about bitcoin is all the time we can have confident like bouncing back of prices at any time. It had happened many times in the past so we never need to get panic nor frustrations on seeing prices falling down and when we are losing our capital virtually.
