Why do some people with 10 million still choose to trade cryptocurrencies?

With 10 million, one shouldn't have to worry about life; one could clearly live simply and happily. Why enter the crypto world and make oneself so stressed?

If someone has 10 million and invests one or two million in cryptocurrencies, it is understandable. However, investing all their money in cryptocurrencies can only be described as greed!

A person should have a stable job, a career, savings, and steadily engage in reliable activities, rather than entering the crypto world in hopes of becoming richer.
