Let's calculate what the transaction fee is

Assuming your principal is 1000u, with 100 times leverage, your position value is 100000u, then your transaction fee is

100000✖️0.0005✖️2=100u, and this is just for a single transaction. If you open positions three times a day, in four days your transaction fees will exceed your principal. Do you still think the transaction fees are low? It's just that you haven't added them up. Each trade may seem small, but the total can be frightening.

So how to reduce it? You just need to fill in the referral ID.
