The answer to this question depends on the individual's trading strategy and risk tolerance. While it is true that some altcoins, such as Doge and SHIB, have outperformed Bitcoin in the short term, it is important to remember that these gains are often short-lived and highly volatile. Therefore, for most investors, it is generally advisable to hold Bitcoin as a long-term investment, as its value has proven to be more stable and reliable in the long run. However, if an investor is willing to take on more risk and has the knowledge and experience to successfully time the market, then trading altcoins can be an effective way to potentially generate higher returns.
