Many times prediction goes wrong and some so called experts influence people in the wrong direction. When everyone was waiting for Bitcoin to cross the 2017 ATH and it seemed very difficult to cross. Because at that time the market price of Bitcoin was not increasing much. But the reality is that at that time the big investors silently bought the bitcoins of the weak hand traders. Those who sold their held bitcoins at the time now understand their mistake.
You are right, weak hands always sell at worst time, some were sold for $ 30k and now they are sorry, but they are waiting for the price to go down again, which is difficult for me, some YouTubers who are said to be experts predict that the price of Bitcoin will go down, but I think that for now it will not be possible, many celebrities and institutional investment has entered the market, in 2017 it was another time, now 2021 everything is different.
