Add one yuan

Recently, the limit price for brushing Alpha can be calculated based on the completed transactions. Actually, it's about 4 times. I usually use 750-850u for a trading volume of 70,000 a day. After buying 21 times and selling with limit orders, the price is basically balanced. Overall wear is less than 2u-4u. It's less than wallet wear. Recently, I don't recommend any specific coins for trading competitions. Coins with small fluctuations are quite easy to brush.
