If BTC experiences another bull market, this time I'll conservatively adopt a dollar-cost averaging approach, abandoning the heavy-position, all-in strategy of the previous two rounds. Buy at the ideal price (BTC breaks the 7-5 range) and dollar-cost average 3-5 layers of capital. The market is somewhat unpredictable due to the presence of US funds, but I believe BTC is a good thing, at least I believe there will be another bull market in the future. The bottom of this bear market is similar to the top of the recent bull market, as I mentioned before. I'm not entirely certain. When exiting at the top, I'll choose to do so in batches; when buying at the bottom, I'll also choose to do so in batches.
