BlackRock's recent filing for a bitcoin exchange-traded fund (ETF) contributed to the cryptocurrency market's third consecutive day of growth. Bitcoin increased 5% to $30,326, and Ethereum surpassed $1,900. Bitcoin's trading volume rose 25% to about $31.48 billion within the past 24 hours. Other cryptocurrencies such as Cardano, Dogecoin, Shiba Inu, and Litecoin also saw a surge of over 7%. The global cryptocurrency market cap rose by 5% to $1.18 trillion within the last day. Experts believe that Bitcoin has entered a key resistance zone that could help it break above $32,500 in the coming weeks, spurred by positive investor sentiment.
