Starting today, until June 2028, do not buy any coins other than Bitcoin! The reasons are as follows:
Reason 1: Bitcoin has been rising for 1000 days. In the past decade-long cycles, it has never had a rising record exceeding 1100 days;
Reason 2: 99% of altcoins cannot outperform Bitcoin in a bear market, and new coins (coins launched after 2023) cannot outperform Bitcoin within 5 years.
