China has been expanding use of digital currencies as it promotes wider use of its yuan, or renminbi, to reflect its status as the world's second-largest economy. It also wants to challenge the dominance of the U.S. dollar in international trade and finance. Restrictions on access to Chinese financial markets and limits on convertibility of the yuan, or "people's money," are big obstacles blocking its global use. Still, Hong Kong already has stablecoin regulations and some Chinese experts are pushing for regulations to prepare for a possible stablecoin pegged to the yuan. Such moves follow President Donald Trump's signing last month of a law regulating stablecoins.
The headline-grabbing tale of an Italian man who said he was kidnapped and tortured for weeks inside an upscale Manhattan townhouse by captors seeking his bitcoin highlights a dark corner of the cryptocurrency world: the threat of violence by thieves seeking digital assets. The alleged attempted robbery is known as a "wrench attack." It's a name popularized by an online comic that mocked how easily high-tech security can be undone by hitting someone with a wrench until they give up passwords. Wrench attacks are on the rise thanks in part to cryptocurrency's move into mainstream finance, experts say.
