That’s certainly the reason why most beginners are not advised to engage in trading because they don’t even know how to start trading at a small amount. They often think that if they trade with small capital, the profits will not be worth the risk. But the reality is, all beginners should start trading at a smaller amount so that the risk of losing will be somehow manageable. Otherwise, if they conclude trading at a huge amount, the chances to lose is very high so once they trade and lose, they might find it hard to recover their losses and might not be capable of trading once again.
That is a very common problem with newbies traders, they want to win and they want their wins to be big and fast, and while there is nothing wrong with those desires, as who would not like for their trades to go their way, it is an unrealistic goal taking into account their level of skill, so they should start slow and use a very small amount of money on their trades so they can learn all what they can while minimizing their losses, but as you may guess those newbies do not really do this and they have to learn the hard way why trading is one of the most difficult ways to make money that exist.
Most newbies learn it the hard way, they either hear an influencer praising the cryptocurrency market and how profitable it can be for someone, or have seen a story of a person getting significant gains after investing in a meme coin, and they simply get excited after that and think that they can achieve great things in a very short period of time from here without knowing anything about or considering the risks involved with the investments.
They mostly lack the ability to do their own research, they expect a lot of things and don't see the negative aspects at all. Once they enter the market, take their first couple of trades, get some loss because they don't know much, that is when they come to know the reality that it is not as easy as they might have thought.
