比特币暴跌18%，受25亿美元清算影响跌至6万美元

The assessment is based on overwhelming and consistent evidence from multiple high-authority sources that directly corroborate both parts of the statement. Several primary sources, including specialized crypto publication CoinDesk, major exchange Coinbase, and widely distributed news outlet Yahoo Finance, explicitly state that Bitcoin's price fell below $68,000 and that this event coincided with crypto market liquidations surpassing $1 billion. This creates a strong, consistent narrative across credible outlets.Further sources, while not perfectly aligned with every detail of the statement, add significant weight to the claim. For instance, reports of liquidations totaling as high as $1.7 billion strongly support the "totaled $1 billion" clause, as this figure is well above the stated threshold. The data aggregator CoinGlass is repeatedly cited as the primary source for this liquidation data, lending high credibility to the figures reported by the news outlets.There are a few sources that mention different price points (e.g., below $81,000 or $80,000) and liquidation amounts. However, these appear to be describing different market events on different dates, which is common in the volatile cryptocurrency market. They do not directly contradict the specific event described in the statement and the primary supporting sources; rather, they report on separate instances of volatility. Therefore, they do not undermine the strong, direct evidence supporting the claim.
