What can you do with a blockchain token that is classified as a security?

In a way, this is potentially the clearest example of what you can expect if a token is found to be a security: given the current exchange ecosystem, it will likely be inaccessible to US users, but worldwide. Will be available for trading to anyone. With a Bithumb, Bitstamp or KuCoin account (and in the US, if you have a VPN). Astute readers may note that I left Binance – the largest US exchange, by far – out of that list. This is not only because it is currently being sued by the SEC, but to make the next point.
