You may not know that in spot trading you can enter any order you want. If you think I will place the order too low, you can place it on the spot trading platform. Later, if the market falls and your order is completed, you can sell at a higher price. Why should I hesitate to pay a small fee if I am profiting here. But you can never do it in convert system. Convert system requires you to convert directly from Instant Market. The Convert system also has hidden fees that you may not catch.
