I think one of the main issues with FUD is that it's often shared around without the person even reading the article. Someone will post some FUD (usually nonsense), and then people will be quick to panic without stepping back and assessing what is actually going on. This spreads like wildfire, and the markets respond accordingly.

The most recent example for me was the Binance 'hack'. People were sharing articles and posts as if it were the end of crypto. In reality, Binance acted brilliantly; spotting unusual activity, halting withdrawals, and protecting funds.
