How did you know? There is no way to know if Bitcoin can touch again to 14k if you know what happened in the past about the price of bitcoin there is also someone predicting that the price of Bitcoin won't drop below 10k but after a few months, it started to drop below 10k. So there is still a possibility it may drop to 14k or lower than that.
Anything can happen, but that is based on my analyses and how the price of bitcoin has been in history. But let me put it like this: if the price of bitcoin get to $16000 again, will you not buy enough? If you did not, it would only be a missed opportunity of the next bull run, although the price may still fall again and reach $16000, but getting below $14000 is highly not likely at all.
What does mean by this FUD actually? As I know it's something like a piece of false news but hyped on the internet. So it could good news or bad news. Most of the time it acts as bad news I assume. But you are suggesting buying bitcoin when FUD is upcoming. So a Big chance to lose your fund because most of the time FUDs are bad news and help to crash the market as I know.
Did you remember the China FUD on bitcoin and crypto ban? The price crashed from $46000 to $29800 at that time. Did you remember the one that happened during FTX implosion? Bitcoin price crashed from $22800 to $15500. I think that is what OP meant. During the FUD, the price will fall significantly. After the FUD, you can still wait, but you will notice that bitcoin is not going beyond certain price again after massive bear market.
