This week’s blockbuster IPO of Circle, a leading issuer of stablecoins, shows how crypto is increasingly going mainstream. Here’s how to invest.

Circle Internet is betting on wider use of its USDC digital currency, which is redeemable one-for-one with the U.S. dollar.

Circle, the company behind the $61 billion stablecoin USDC, made a roaring debut on the New York Stock Exchange Thursday, becoming the first stablecoin issuer to go public and making CEO and cofounder Jeremy Allaire a billionaire.
