Other brokers require commissions except Poipex

When a friend of mine traded with another platform, commissions were deducted from each revenue. But Poipex doesn’t deduct commissions. How can they operate without deducting commissions? This must be a way of inducing investors to deposit and then rejecting withdrawal. I can accept commissions deducted from each revenue and then withdrawing money normally. Below is a screenshot of commissions of about 10% charged by another platform for reference, and I hope to be contacted as soon as possible to coordinate the withdrawal amount.
