$18,000 or $8000 or $800...

It is difficult to state what will happen and which circumstances will lead to someone hold or sell but what can be said is that there was and will always be panic buying and selling because of FUD. Whether stocks and shares, crypto or anything else in a free market, FUD does play a part.

Those that sell now to buy later do not always get what they want as it really works only when the selling price is high enough to entice a sale at a time when a price drop is expected. I would advise to not play that game as it can backfire spectacularly.
