8月25日，比特币价格继续走高，盘中一度突破8.1万美元关口，重返今年5月以来高位。
此前，比特币已连续突破7万美元、7.5万美元及8万美元等整数关口，延续近期快速上涨态势。比特币走强也带动加密货币市场整体上涨，以太坊（ETH）、Solana等主流加密货币同步走高。
本轮加密货币上涨受到多重因素推动。近段时间，美国长期国债收益率回落、美元走弱，带动市场风险偏好改善；与此同时，美国比特币现货ETF资金重新流入，叠加前期大量空头头寸被迫平仓，进一步放大比特币涨幅。
在监管层面，美国数字资产市场立法继续推进，也强化了市场对监管环境改善的预期。不过，在短期快速上涨后，比特币价格波动明显加大，8万美元上方能否形成持续买盘仍受到市场关注。
