It is usually observed that as bitcoin rises, so does the altcoins and if bitcoin falls then it goes the same way for altcoins. Investors are very dependent on bitcoin and they think any movement from bitcoin reflects the overall market.

If they do not trust bitcoin the less they trust altcoins. The only way I can think of that could make altcoins be more valuable than bitcoin is when bitcoin goes down and instead of investors losing hope for the overall crypto market, they focus on altcoins..p
