I have created an intelligent combination for myself! A private ETF consisting of Crypto, Gold, US Stocks, and Cash. I prefer the OKX feature because it allows me to combine cryptocurrencies, stock tokens, gold, ETFs, and USDT into the same portfolio, which was not possible in the past. It is equivalent to creating a customized portfolio fund for oneself, which can automatically customize and purchase one's desired digital assets by putting them into it, and automatically balance: Asset increase → excessive weight → automatic selling of a small amount; Asset decline → weight reduction → automatic replenishment. I have studied the rules and found that the official currently provides two methods: proportional balance and timed balance; When the proportional mode reaches the set deviation, it will be executed, and even retested every 5 minutes after balancing once; The timed mode is checked at a fixed cycle and executed only when the deviation exceeds 3%. I chose timed balancing instead of frequent proportional balancing because my goal is long-term asset allocation, not high-frequency mean regression between BTC, HYPE, and HOOD.
