Recently, the limited order price for Alpha can be calculated based on completed transactions. Actually, it’s about 4 times. I generally use 750-850 USDT to process a daily transaction volume of 70,000. After buying 21 times and selling with limit orders, the price is basically balanced. Overall wear is less than 2-4 USDT. It’s less than wallet wear. Recently, I don't recommend any specific coins for trading competitions, but coins with small fluctuations are quite good for processing.
