外媒报道称,资深交易员 Peter Brandt 公开质疑币安的交易基础设施。导火索是比特币在 8 月 22 日的一次局部异常下探:当时其他主流平台价格仍接近 7.9 万美元,币安 BTC/USD 一度在数秒内跌至 7.25 万美元,并迅速拉出长下影线。

跨平台价差一度扩大

按报道给出的对比,同一时段 Coinbase 的最低价约为 7.58 万美元。这意味着两家交易所之间一度出现约 3300 美元的价差。Brandt 认为,这种只出现在单一平台的剧烈偏离,足以触发该平台用户的止损单与杠杆仓位强平。

他还提到,类似情况并非首次出现,并点名币安过去也曾发生过严重的“扫损”事件。文章将这次波动描述为一次局部闪崩,而不是整个比特币市场同步下跌。

局部流动性放大跌幅

报道指出,加密市场流动性分散在不同交易平台。若某一平台突然遭遇大额市价卖单,本地订单簿可能在短时间内缺少足够买盘,价格就会先在该平台快速下探。

在此基础上,杠杆仓位的自动强平会继续向市场抛出卖单,进一步压低成交价,形成连锁反应。也就是说,最初的流动性缺口,可能被平台内部的强平机制继续放大,最终形成远低于全市场水平的瞬时低点。

争议指向触发价格机制

文章认为,这次事件再次暴露出以单一交易所“最新成交价”触发保护单的风险。尤其在流动性不足或局部波动放大时,止损与强平可能只在个别平台集中发生,而其他交易所并未出现同等幅度的下跌。

Brandt 借此质疑,交易平台在极端波动下是否为用户提供了足够稳健的保护机制。报道提到,相比直接锚定本地最新成交价,参考更广泛市场的标记价格,通常更能降低孤立插针对用户仓位的冲击。
