China's growing pile of cryptocurrencies seized from illegal transactions is prompting local governments to find ways to dispose of the hoard and spurring calls from courts and the financial industry for better regulation. Together with senior judges and police, attorneys are debating changes to rules they said will soon change the way confiscated virtual currencies are treated. That could be a game-changer for China's crypto industry, and comes at a time of heightened Sino-U.S. tensions in Donald Trump's second presidency, coinciding with Trump's plans to deregulate cryptocurrencies and build a bitcoin reserve.
