$AT at This trading competition is quite competitive. It's recommended to top up to a trading amount of 2000 (buy 1000u, sell 1000u). For those who previously brushed the minimum guarantee (501u buy, 501u sell), top up again, then buy 501u to buy and sell. Based on previous deductions, if you brush less, you will only randomly get the lowest minimum guarantee 🤑. Let's try 2000 this time; the cost for 2000 is approximately 2u.
