This was good news, and also a bit painful to watch as she announced it. People are so (rightfully) mistrusting of Robinhood that you could hear the tension in the air. I'm in favor of anything that increases adoption, but Robinhood has a pretty bad track record of doing some dirty deeds, famously with the whole AMC/Gamestop debacle.
They said "Control your Bitcoin" in the ad, but I'd have to see it to believe it.
