Putin claims that Bitcoin and other cryptocurrencies "have the right to exist" and can be used as a means of settlement for transfers, although he considers that, for now, they are too volatile for oil contracts or other critical commodities. He also stated that Bitcoin cannot be banned, referring to its distributed technological nature. While he supports projects like the digital ruble, he has also warned about the high energy consumption of mining, which requires regulation to avoid power outages in specific regions. In summary: Putin sees cryptocurrencies as inevitable, useful for international trade and evading sanctions, but requires control and regulation.
