How many scammers are there who cheat you with transaction fees?
First, when you create an account and use their referral code, they earn money.
Second, the fees are very small; for example, if I make a profit of 3k, the fee is 117u, and the fee received is 145u, meaning I still have a positive transaction fee.
Third, the total transaction fee includes the commission every time you close a trade; only when there's a profit or loss will they deduct it.
You don't get rich from a few coins; you're just making them richer 🤣
In every transaction, you are also charged fees for them.
