IMO, this is a good indicator for people to maintain the balance and since the method is pointed out by investopedia, there must be a huge number of investors following this technique. Have you heard about self-esteem prophecy? When there are a large number of people who believe in a same prediction, it is likely to happen.
The majority here push the HODL narrative 24/7. Confirmation bias, they close their eyes and mind when BTC goes down, and yell at the moon when prices rises.
During a collapse, consensus of silence is demanded, otherwise you be a 'hater', so say the bitcoin cult
The cult leader Musk, just sold his stake, but its ok that he doesn't HODL. Why is that? Your supposed to HODL, not him. If HODL is such a good idea, then why did Musk sell? Why is it OK, for Musk to take profit, but not you?
Cults always do this the leader will tell you all to practice Chasity, and then the same leader will be having sex with every nubile in the cult.
Nothing is more powerful than being ostracized, here being called a 'hater'
