据 Woofun AI 消息，7月28日比特币价格回落至63,350美元附近，正与50日简单移动平均线（63,275美元）展开关键博弈。
技术面上，7月27日分析报告指出的强劲突破走势因未能触及67,370美元而失效。当前市场焦点在于63,300美元至63,600美元的支撑区间，若该防线稳固，BTC有望回升至65,000美元上方；反之，若日线收盘确认跌破均线，看跌趋势将延续，62,000美元将面临直接威胁。
资金面压力主要源于美国比特币现货ETF的持续撤资。7月23日、24日及27日分别录得2.2518亿美元、2.4008亿美元和1,164万美元的净流出，三日合计达4.769亿美元。
这一数据与此前一周3,379万美元的温和净流入形成鲜明对比，显示前期买入势头已随BTC难以站稳65,000美元而消退。Woofun AI 整理数据显示，尽管短期需求疲软，但链上供应端呈现紧缩态势。
CryptoQuant报告揭示了过去六个月的结构性变化：交易所持仓从278.3万枚降至270.5万枚，减少约78,000枚。持有者将资产转入自托管账户导致可交易流动性下降，这种供需失衡虽未解决短期抛压，但一旦买盘回归，稀缺的现货供应可能引发更剧烈的价格波动。
