You can do it without any problem, as long as the conversion is not at the Whale level

Good evening, I wanted to ask you, who know everything, I have been on Binance for a short time, as I don't know how to trade, but I have used the method of converting a cryptocurrency when it goes down and converting to USDT when it goes up, and I have made 20 and 40 dollars, I only did it 2 times. I ask if what I am doing is correct or will I have any sanction or I don't know because trading is very difficult for me. I would like to know if I can continue with the method of just converting. Opinions please, thank you.
