Investigators said the Regalados, who ran a cryptocurrency marketplace called the Kingdom Wealth Exchange, used at least $1.3 million of those funds to support a lavish lifestyle that included tens of thousands of dollars spent on vacations, jewelry, luxury handbags, cosmetic dentistry, clothes and home renovations. The two, who shut down the exchange Nov. 1, also are accused of using some of the money to finance the purchase of a Range Rover.
