Bitcoin briefly rose above $64,000 within five minutes on June 8, setting off a cluster of large short liquidations as prices moved through the $63,000-$64,000 band. HyperInsight said the move forced several bearish leveraged positions to close, with Hyperliquid recording 10 liquidations of more than $1 million in rapid succession. The largest liquidation was $6.06 million at a liquidation price of $63,224. HyperInsight also said whale positioning remained highly tactical that day, with no BTC long position larger than $10 million being held for more than an hour. As of publication, the largest BTC long holder, identified as "BTC OG insider whale," was sitting on a $16.3 million unrealized loss, while the second-largest BTC short holder had placed a buy order at $60,093 to exit a $26.25 million short at breakeven after accumulating more than $1.25 million in unrealized losses. Separately, HyperInsight had identified a single whale opening a position worth more than $10 million on Hyperliquid on June 8, using $410,000 and 40x leverage to short 257.9 BTC worth about $16.2 million near a $62,000 price. Liquidations occur when exchanges automatically close leveraged trades after losses breach margin requirements.
