实时更新：比特币价格上涨至$81,000，主要加密货币在Fed决策前大幅上涨

Bitcoin experienced a significant price increase, climbing above the $81,000 mark, as a wider rally swept across major cryptocurrencies. Tokens like HYPE and ZEC also saw substantial gains, with nearly all top digital assets trading in the green. This broad market upturn occurred in the hours leading up to the Federal Reserve's crucial interest rate decision. The pre-announcement rally suggests that investors were anticipating a favorable outcome from the Fed, likely a decision to hold rates steady, which typically boosts risk assets. Such collective market movements often reflect strong investor confidence and a willingness to take on more risk in anticipation of positive macroeconomic signals.
