According to historical data, altcoins peak around 547 days after each Bitcoin block reward halving. Bitcoin's most recent halving occurred on April 19, 2024, so the date 547 days later is October 17, 2025. By this logic, it is recommended to sell all altcoins on October 17, 2025, rather than today. This time point may be the strategy for the best gains based on historical trends. ​​​
