Before investing, you need to have a specific plan and set the price to sell after buying. I think that if you do this way, you will control your greed and ensure a good return on that investment. In fact new investors are often very greedy and they often wait to make a higher profit and when the market falls they tend to panic sell more. I always advise people and always share their knowledge about investment but they usually only care about profit so it will be difficult to mention this.

Personally, I always divide capital clearly in my investment and always control my profits. Of course always follow the original plan and always in the best state when investing.
