Scalping, FYI, is only for those who have an understanding of trading. Most of those who work there are professional traders or have deep experience in trading activity. Those who don't know trading or newbies who only want to make money right away are not allowed here.
Scalping is necessary from time to time. It is necessary to monitor the chart graph so that they know whether they need to adjust or not in the set-up they have made, whether it is buy or sell. And you should also know which category you fall into as a crypto trader.
You are right that only people who have complete knowledge about trading can make profit in scalping. An expert trader creates a complete setup for his trades where to buy and where to exit. Must have chart knowledge and thorough chart analysis. So that they know at which point they have to enter. Whenever the market falls there is a good opportunity for scalping, but it is also very important to know that there should be a proper gap between our first entry and the second entry. Newbies who don't know how to trade need to be very careful while scalping here, as they may end up losing instead of making a profit. Making money while scalping is not that easy, it requires a lot of experience and skill. However, this is an excellent and successful strategy that will give us good returns.
