Why is it said that beginners should not frequently open positions in a volatile market⁉️

The brother below is the best example. I heard him narrate during the live stream that he blindly followed other teachers to open a long position, setting the stop loss at 3450, and almost suffered a huge loss.

Opening a position unreasonably, along with an unreasonable stop loss setting, destined that this trade would not be a successful one☝️

In the market, there are many teachers who lead to losses with just a superficial understanding. One must be cautious in a bull market; if you follow the right person, you can steadily make money in a bull market. If you follow the wrong person, not only will you miss out on a bull market, but it is also easy to lose everything.
