The first trick to reduce fees: rebates (the most direct)
To encourage new users, the platform will distribute a portion of the fees generated by new users to the referrer in the form of a "rebate." Referrers set different rebate rates to return to users. If you did not fill in a valid invitation code when you registered, this rebate will be fully submitted to the platform.

Rebates are an additional return independent of trading gains and losses. In other words, regardless of whether your trade is profitable or not, the saved fees will return to your account. #返佣
