With the very fastly-changing crypto market, I think sometimes trading can help traders get huge money within short period (in bull market), but sometimes they might lose huge money, too (within bear market). Therefore, trading is not the only one one person should do. They should spread their options out to short-term (tradings) and long-term (investing) in order to keep them safe and bring convenience when they need to sell their crypto to get money for daily stuffs.
