To make a profit you have to take a lot of risks that you have to invest and without fear of losing because often you lose someone who only wants to make a profit, they will not make any

As a beginner and I do not know how to trade and I have never traded, sold or bought and I do not even know how to sell a currency to someone and how to receive the profits of any currency, but for more than a month on this platform I saw that the best currency for quick trading and earning even a little is the BNB# currency. It goes up and down and this is a beautiful currency. I see it for those who trade immediately. Buy if it goes below 698$ and sell above 710$ . If you earn even one or two dollars according to the amount you have, it is much better for you. Are my words correct for knowledgeable people? Is this method effective for profit on this platform?
