Powers On... is a monthly opinion column from Marc Powers, who spent much of his 40-year legal career working with complex securities-related cases in the United States after a stint with the SEC. He is now an adjunct professor at Florida International University College of Law, where he teaches a course on “Blockchain, Crypto and Regulatory Considerations.” While attending the Bitcoin 2021 conference in Miami two weeks ago, several things struck me as interesting and significant. While many others have already reported on the conference, my focus will be on a handful of comments or events that I believe are important for the cryptocurrency and blockchain space.
