In 2018, ICOs, or initial coin offerings, were the hot new thing in startup fundraising. A company could raise money by selling you a little bit of value or equity in the form of a digital coin, similar to bitcoin but specific to that company. ICOs raised about $22 billion, or so we think. It's hard to know because the practice has been unregulated. A lot of them turned out to be scams. The Securities and Exchange Commission started fining celebrities like Floyd Mayweather and DJ Khaled over sketchy paid promotions for ICOs. It got weird, and now it's regulation time. That means that future ICOs and their digital coins might start to look a lot more like good old-fashioned stock, except traded on the blockchain, and that has big ramifications for Wall Street. Molly Wood talks with Kristen Howell, a partner with the law firm Fox Rothschild who helps companies create ICOs.  Today's show is sponsored by Kronos, Mozilla/Firefox and Lenovo for Small Business.
