Some friends are concerned about which company the profits in the table belong to. I have been doing it for a while, mainly on Binance and OKX, and occasionally on Bitget. Let's compare Binance and OKX first: First, let's take a look at the T+1 model. There is still some difference between Binance and OKX. For example, both sell PUT at $76000, and Binance's interest rate will be higher. However, OKX's price range is narrower, and the closer it is to the current price, the higher OKX's return will be, such as $77000. So generally speaking, if it is far from the current price, I will use Binance more, while if it is near the current price, using OKX will yield slightly higher returns. The pattern of T+2 is also similar, with higher returns for OKX as it approaches the current price, and higher returns for Binance as it moves away from the current price. So this combination depends on the individual. Then Binacne and OKX both have their own characteristics. For example, Binance has dual currency large investments, where you can use large investments by purchasing at least $5000 worth of Bitcoin or selling at least 0.1 BTC. The biggest advantage of large investments is that you can define the price and time you want to buy and sell, and obtain third-party quotes. This feature is quite good and I am currently mainly using it, and the third-party quote will be slightly higher than the interest offered by Binance dual currency. The biggest feature of OKX is that it supports more flexible delivery times. Binance operates from midnight to the next day, and there are no deliveries on weekends. But OKX can be traded before noon, and OKX can be delivered on weekends. In terms of time, OKX is more convenient and flexible.
