This is the most prominent problem faced by over-enthousiasmic investors. I know someone who closed his grocery store, which was generating good daily returns, sold his remaining stock, and invested the entire amount in Doge coin, following the hype sparked by Elon Musk's tweets about the meme token Doge. What happened next was that he bought at a price considered high compared to the pre-wave price and was forced to sell at a huge loss, preventing him from even reopening his store. He wasn't directly influenced by Musk's tweets, but rather by his acquaintances, who repeatedly told him they were making significant returns from investing in cryptocurrencies, citing the success of Dodge's investment without mentioning the risk.
