Coldcard 冷钱包安全事件后,市场对自托管风险的讨论明显升温。美国上市比特币现货 ETF 上周录得逾 8.5 亿美元净流入,创 4 月以来最强单周表现。资金流入发生在币价缺乏明显反弹的阶段,显示部分投资者正在调整持有方式。

冷钱包事件引发关注

据报道,加拿大 Coinkite 旗下 Coldcard 钱包的部分固件版本存在缺陷,导致相关钱包使用的安全信息可预测性高于预期。攻击者无需实际接触设备,便可能取得受影响钱包控制权并转走比特币。

报道提到,此次事件涉及约 1.3 亿美元比特币被盗。Coinkite 表示,正协助受影响客户处理后续问题。

ETF 资金流入升温

彭博行业研究分析师 Eric Balchunas 认为,这起事件可能让比特币现货 ETF 对部分投资者更具吸引力,尤其是长期持有者。对这部分资金而言,受监管产品提供了无需自行保管私钥的持仓渠道。

上周美国上市比特币 ETF 的资金流入超过 8.5 亿美元,为近四个月最佳单周表现。不过,这轮流入并未伴随价格同步走强。比特币周一一度跌超 2%,至 63830 美元附近,自 6 月以来大致维持在 6 万至 6.7 万美元区间波动。

  • 比特币 ETF 周流入:逾 8.5 亿美元
  • 被盗规模:约 1.3 亿美元比特币
  • 价格区间:6 万至 6.7 万美元

资金转向机构产品

Wave Digital Assets 国际投资组合管理主管 Rajiv Sawhney 表示,这一变化反映出边际资金正从自托管转向机构化产品。对部分投资者来说,ETF 的吸引力不只在于价格敞口,也在于托管责任转移给大型金融机构。

不过,转向 ETF 并不意味着风险消失。ETF 托管机构同样可能遭遇安全问题,投资者也会失去对比特币的直接控制权。只是相较个人保管,受监管机构通常拥有更完整的安全团队、内部流程和外部监管约束。

Balchunas 认为,如果 ETF 托管环节出现类似事件,通常会更快触发监管审查和执法调查。这种制度层面的保护,可能是部分投资者在当前环境下重新评估持仓方式的重要原因。
