Cryptocurrency markets are experiencing significant volatility following the Federal Reserve's decision to cut interest rates and revive quantitative easing, alongside a global liquidity expansion. Bitcoin's price fell to $86,523, while Ethereum dropped to $2,836, influenced by Japan's proposed 20% flat tax on crypto gains. In the altcoin sector, small-cap tokens like $TRADOOR and $ZND surged by 41%, whereas major altcoins such as $ZEC and $ENA saw declines of 22% and 17%, respectively. Regulatory developments include the People's Bank of China maintaining its stance against recognizing cryptocurrencies as legal tender, and BlackRock's Bitcoin ETF emerging as a significant revenue source. Additionally, the decentralized Cocoon network has been launched, adding to the evolving crypto landscape.
