Wu said that he learned that the wallet address marked as "US government" transferred 11.84 BTC worth $72,600 to 3KHnTqDh2LUmzYe8hgSnxY2QHFcNmuuso9 at 21:02. This may be a small test before a large transfer. The wallet holds the seized funds of Estonian crypto entrepreneurs Potapenko and Turogin. Previously, Sergei Potapenko and Ivan Turõgin were accused of operating a $575 million crypto Ponzi scheme involving the fraudulent cryptocurrency mining service Hashflare.
