For me, most of the people said its correct. The first list in my mind before entering trading cryptos is known as the nature of the trading industry, like what is the difference of trading crypto to a stock market ( which is cryptos price is very fluctuating, and it can be volatile by an hour ). The second thing is you should learn the basics of trading and gaining some knowledge. The third one doesn't be afraid to ask, to try, to explore, to failed ( at first attempt) because it will help you to become a better trader. The most important is don’t spend some money that you can’t afford to lose because in this kind of industry there's no easy money, especially if you don't want to make any effort.
