A previously dormant Bitcoin wallet, identified as bc1ql7c, has transferred 6,500 BTC, valued at approximately $694 million, to new wallets. This significant movement comes after three years of inactivity. The BTC was originally received from Russian crypto entrepreneur Bilyuchenko, also known as Ivanov, who is accused of co-founding the BTC-e and WEX exchanges and laundering bitcoins stolen from Mt. Gox.
