so I wan to know if it's right for the person to begin trading?
It's okay for a beginner to trade, because all professional traders started as beginners. However, what needs to be paid attention to in order to become a trader is that they need to study the market for the instrument they choose, what its characteristics are and carry out back tests, to be able to see how the method they learn can actually work on the market. If they are confident that they can manage positions, carry out TP/SL, and good management on their demo account, they can test on a real account with low money.And if they are successful on a real account with that low amount of money, they can increase their capital slowly and see how their trading progresses. The most important thing is how they can learn and continue to see the development of their trading, not just enter the market and trade as they please.
I believe the OP indirectly wants to know if it is risky for a beginner to trade. But there is not road to riches that there wont be any form of risk and sacrifice. There is always a start from a newbies and soon they will reach there. What should be more important is how will they be able to control their emotions during this growing stage. Of course there will be loss and wins which will cost them to either start over or fall down to some middle part.
