You can get rich quickly on crypto if you are lucky, but get rich without luck requires knowledge and experience of several years, during which you will lose investments.
To trade you need to be mentally prepared and not to panic, monitor the currency exchange rate and news and at the same time there are big risks, the price may drop below the purchasing one for many months. It is also necessary to take into account the complex process of depositing money to the exchange for beginners, as well as paying % when withdrawing funds back.

Given all this, I can agree that crypto is not for guys who want to earn money fast, or become rich in a few month.
