In a development that took businesses by surprise, the Monetary Authority of Singapore said the “provision of physical ATMs” is prohibited. The regulator’s assistant managing director, Loo Siew Lee, didn’t mince her words in Monday’s announcement, warning: “The trading of cryptocurrencies is highly risky and not suitable for the general public.”
