Everyone was stunned when the new mayor of New York City Eric Adams announced he was planning to receive his first three paychecks in Bitcoin, the cryptocurrency that’s been dominating the financial headlines for the past year. The mayor of Miami, Francis Suarez, had already announced he would accept his first paycheck 100% in Bitcoin. The mayoral announcements are still more signs that cryptocurrencies are no longer esoteric investments for the super-rich (or super-crooks) but have entered the financial mainstream. Back in May Deutsche Bank pronounced Bitcoin the third biggest world currency in terms of circulation. Only the euro and the U.S. dollar are bigger.
