When one does not have knowledge about trading and does not have any idea about how trading works he will not be able to profit from trading in any way. Because he will always make the wrong decision, invest in the wrong coin and sell it at the wrong time. But some times due to his luck he may make some profit but not always it happens. Trading is not an easy thing it is a very difficult thing so trading should be done with good understanding
Yes, and a lot of newbies that enter the market tend to ignore this fact mostly because they have been misguided by some influencer on YouTube or some other social media platform or they have seen profit screenshots of people in social media trading groups where people only share their profits and hide their losses and newbies don't understand this and they think all of them are just earning money all the time.
So as you said, it's important for someone to learn trading before they venture into it because it isn't as easy as some might think it is and there can be challenging times ahead of them if one doesn't have any knowledge about the market but starts trading anyway.
