The source of Bitcoin's sudden May sell-off is now clearer. A Pantera Capital partner explicitly identified an Asian mega-trader's forced liquidation in a yen carry trade as the primary trigger. The admission has reignited debates around leverage risk and opaque position concentration in crypto markets.
Yen Carry Meltdown: One Account, 12,000 BTC Dump
According to the partner, the whale had opened a massive long BTC position while shorting the Japanese yen for carry. When the yen spiked violently — USD/JPY swung over 3% in a single session — both legs of the trade cracked. The margin call liquidated roughly 12,000 BTC within 30 minutes, cascading through perpetual swaps and spot markets. Estimated total loss: $430 million. “This wasn't a macro event. It was a physics collapse of one oversized book,” the partner wrote.
BTC Rebounds to $64.8K, Dormant Whale Wakes
Panic buying quickly replaced panic selling. Bitcoin recovered from an intraday low of $63,200 to trade near $64,800 a week later. On-chain sleuths flagged an address that had been idle for over two years suddenly buying 3,600 BTC at an average price of $64,200. Other large holders with >10,000 BTC also added minor positions, signaling conviction among long-term believers.
Metaplanet Japan Doubles Down
Metaplanet, often dubbed “Japan's MicroStrategy,” confirmed it bought another 150 BTC on the day of the crash via OTC at $63,800. The firm's CEO reiterated: “We accumulate for the next cycle. Daily noise is irrelevant.” Its total holdings now exceed 1,200 BTC.
Meanwhile: Trump Alien Speech? Markets Don't Care
In a completely unrelated sideline, a British documentary director claimed Trump will deliver a historical speech at the UN on July 8, 2026, acknowledging extraterrestrial existence. The White House has not confirmed. Crypto traders mostly shrugged. One quip: “If aliens are real, they're probably buying the dip.” No market impact observed.
