MoneyGram to allow retail Bitcoin buying in the US. Crypto adoption among mainstream payment service companies continues to grow, with MoneyGram set to join the list. In a release issued on Wednesday, the global payment service announced a partnership with crypto exchange and Bitcoin (BTC) ATM operator Coinme Inc., to allow United States customers to withdraw their cryptocurrency holdings for cash across its point-of-sale outlets in the country. As part of the announcement, MoneyGram also revealed that customers will be able to buy BTC and crypto in an expansion of the existing crypto-to-cash model pioneered by the almost 20,000 cryptocurrency ATMs around the world. MoneyGram debuting physical Bitcoin-buying across its locations in the U.S. is also another example of fintech and payment service firms warming up to cryptocurrencies.
