Russian President Vladimir Putin has signed a law legalizing crypto mining, with regulations requiring miners to register with the Ministry of Digital Development or adhere to energy limits if unregistered. The law also permits crypto trading but allows the central bank to ban activities it considers risky. A separate pending bill aims to use crypto for international payments to circumvent sanctions. Putin has highlighted Russia's energy surplus as beneficial for mining, which is an energy-intensive process for validating transactions on blockchains. Sources: Decrypt
