Coinbase tried repeatedly to register them with the SEC and was turned away, which seems to be lost on your point.
From the article:
> The SEC will not let crypto companies “come in and register” – we tried.
> The Wells notice comes out of the investigation that we disclosed last summer. Shortly after that investigation began, the SEC asked us if we would be interested in discussing a potential resolution that would include registering some portion of our business with the SEC. We said absolutely yes. Specifically, the SEC asked us to provide our views on what a registration path for Coinbase could look like – because there is no existing way for a crypto exchange to register. We developed and proposed two different registration models. We spent millions of dollars on legal support to build these proposals and repeatedly asked for the SEC’s feedback. We got none. We also reiterated that we stand by our listings process – we don’t list securities today – and repeatedly invited the SEC to raise any questions about any asset at all on our platform. They raised none.
