I just found out that Binance's tradeFi contract used to have free transaction fees for hanging orders, and 0.02250% for eating orders. If this is used for grid trading (grid strategies are all about hanging orders, and transaction fees are also an important part of it), it is probably not bad. It is still suitable to use this strategy for the slow rise of the US stock market. Nowadays, many US stocks, including gold, silver, and more, can be traded on it. The 24-hour trading volume of gold and silver has also increased by more than 1 billion yuan, and there are relatively few stocks. Tesla's 24-hour trading volume is 8.37 million yuan, and there will be much less high-quality assets to play with on it, such as knockoff contracts and funds. Shanzhai will face competition from US stocks, which is almost no advantage. However, contracts in the US stock market are different from holding spot stocks because there are funding fees and holding is a cost. Although the funding rate for stocks is lower than that of BTC and ETH (less than 10%), and dividends cannot be obtained for contracts, it solves the pain points for both the cryptocurrency and US stock markets. The cryptocurrency market does not have high-quality assets, but the US stock market does. The US stock market has high-quality assets but is not easy to bet on, and the US stock contract is the solution to this problem.
