to increase profit opportunities, it is indeed better to divide your assets into several parts in altcoins as well.
Yep, diversifying is a proper way to improve the chance to gain bigger profits. Altcoins can increase more significantly than Bitcoin, sometimes it is just in a short time. Many people have gained millions of dollars from altcoins just for several months. But altcoins also have a bigger risk, the price can drop more severely than Bitcoin. Even some altcoins can be dead coins that have no value anymore. It can happen if we choose altcoins carelessly, no research/analysis.
