If the person entering the crypto trading business is really new and has no knowledge, it is possible, as long as he does not suddenly deposit a large amount of money in an exchange that he will also enter. But he should also study trading at the same time; it is not enough because if he actually trades, he will do it right away.
So at least he can ask questions here, or he can also read first about the basic learnings in trading so that at least he has knowledge in the matter he is involved in.
If they are not willing to take the risk of sacrificing some money then they may never understand trading. Because even if we understand the theory of trading, it will be different when we directly practice it in the market, so like it or not they have to spend some money. They can also first use a demo account to learn what they have to do and learn the features in trading. However, in a demo account we are not taught the mentality because when using a demo account there is no pressure whatsoever in trading. It's different when we use real money, our mentality will definitely have a big influence on what we decide.
Continue to deepen your knowledge if you want to become a good trader, don't be quickly satisfied with the knowledge we have.
If the newbie entering crypto trading is not a risk taker, it is better and better not to try to trade or study here in the field of crypto space.
