because the more money you invest, the greater the risk, and the more you lose, but if you are lucky enough to earn money, of course, the more money you invest, the more you earn. Therefore, if you have a lot of courage, you will naturally earn a lot if you make money. Use the metaphor of supporting yourself to death. If you are timid, you will invest less. Although you say you will lose less, you will earn less, so you will starve to death slowly.
