I think the more useful function should be grid trading. This trading method makes investment behavior more rational and scientific with the help of program algorithms. It is well known that people will fluctuate emotionally when they see the rise or fall of cryptocurrencies. At this time, investment behavior becomes less rational. Grid trading can help users scientifically buy low and sell high. It is a very good feature that can minimize the potential risks in investment. There are not many exchanges that have launched this function. Only well-known first-line exchanges such as ZB.com, Binance, and Huobi are able to implement it.
