$BTC Bitcoin (BTC) serves as a barometer for the cryptocurrency market, and its rise usually drives the prices of altcoins higher. This is because an increase in Bitcoin can boost overall market confidence and attract more funds into the crypto market. At the same time, some investors may turn to altcoins in pursuit of higher returns when Bitcoin's growth rate starts to slow. However, altcoins are more volatile and carry higher risks, so investors must carefully assess market dynamics to avoid blindly chasing prices. Under the influence of Bitcoin, altcoins may see short-term upward opportunities, but timing and risk diversification strategies must be considered.
