Timing is crucial when bottom-fishing. My idea is to start with tentative positions, taking small trades to explore the market, rather than going all in at once. The key depends on Japan's interest rate hike actions; once this data is released, it can influence market sentiment. The safest approach is still to wait until the US stock market opens and observe how the major indices react, then look for signals. The real opportunity window is in the early hours of the night, when the trends of #大户持仓动态 and $BTC will be clearer. Building positions gradually is always safer than a one-time bottom-fishing, and managing risk is the most important.
