Popular U.S.-based brokerage platform Robinhood (HOOD) on Thursday started letting customers in the European Union (EU) trade crypto, hailing the region’s comprehensive digital asset rules. To spur customers to use the service, Robinhood will credit a percentage of their trading volume back every month, paid in bitcoin (BTC), according to a Thursday blog post. And users can earn more BTC for referring new customers. This expansion debuts as cryptocurrencies have been rallying after a brutal bear market, recovering to a $1.5 trillion total market capitalization, the highest level since May 2022. Rising trading volumes also mean more revenue for trading platforms.
