According to @ai_9684xtpa, the Cumberland DRW-related address, which had been dormant for three years, recharged 650.93 BTC to Coinbase 4 hours ago (when the BTC price was at its peak), worth $41.96 million. Tracing back the source of funds, it was found that this part of BTC was collected from multiple DRW addresses six years ago, with an average price of only about $4,000; if it is sold this time, the profit will be about 15 times (recharge price of $64,463), equivalent to about $39.35 million.
