“Everything other than bitcoin,” Gensler told me, “you can find a website, you can find a group of entrepreneurs, they might set up their legal entities in a tax haven offshore, they might have a foundation, they might lawyer it up to try to arbitrage and make it hard jurisdictionally or so forth.” In other words, there are people behind these cryptocurrencies using a variety of complex and legally opaque mechanisms, but at the most basic level, they are trying to promote their tokens and entice investors. (Bitcoin, because of its unique history and creation story, is fundamentally different from other crypto projects in this respect.)
