according to Lookonchain monitoring, the wallet address "bc1ql7c" was activated after three years of silence, and just transferred all 6,500 BTC (worth 694 million USD) in the wallet to a new address. These 6,500 BTC were originally obtained from Ivanov (Bilyuchenko) three years ago. Ivanov (also known as Bilyuchenko) is a Russian cryptocurrency entrepreneur accused of co-founding the BTC-e and WEX trading platforms and laundering hundreds of thousands of bitcoins stolen from Mt. Gox in the past.
