At the end it depends on what you are looking, some are looking to make fortunes with crypto but some other are just looking for better returns than the ones the stock market can give, the stock market can give something between 6 to 10 percent per year and bitcoin and ethereum give way better returns than that, so that may be enough for them since they are not willing to take greater risks.
