On January 5th, it was reported that Russian banker Mikhail Klyukin, who was sanctioned by the United States, has sold his shares worth 15 million pounds in the cryptocurrency company Copper. Mikhail Klyukin was sanctioned due to his membership in the supervisory board of the Russian loan institution Sovcombank. The United States prohibits the use of the US dollar in financial transactions with sanctioned individuals and also prohibits US citizens from participating, but it has no jurisdiction over the use of other currencies or foreign citizens doing business with them.
