The price increase of Bitcoin (BTC) typically triggers a chain reaction in the market, leading to a collective rise in altcoins. This is because the rise in Bitcoin enhances investor confidence and attracts more funds into the cryptocurrency market. When Bitcoin dominates, altcoins often experience a rebound. However, the magnitude and pace of altcoin increases depend on the degree of fund diversion and changes in market sentiment, with some strong projects potentially seeing more significant gains. Investors should consider Bitcoin's trends alongside the fundamentals of altcoins when positioning themselves, to manage risks effectively and seize potential profit opportunities.
