Many new investors are naive enough to assume that if an investment is profitable for someone else, it can also be profitable for them. They think it's that simple. This is usually the case with businesses or investments in valuable assets. Even these investments, which may seem intuitive and don't require a lot of experience or knowledge, require a minimum of experience in the field before venturing into a must do experimental stage.
Most of the time that's the case of those newcomers who got hook with how the trend works, most of them because of the current hypes they also start to engage with the same business and unfortunate things happened after, it's always your good judgement and good skills, knowledge and patience in learning the process before stepping into any business that you are wanting to begin / start.
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.
