The tokens are not illegal. But centralized exchanges offering them (if they are indeed securities) is illegal. Their utility and store of value is unchanged. And this does not affect decentralized exchanges AFAI.

These cryptocurrencies still need to interact with fiat for growth. It remains to be seen if adoption outside of the U.S. will continue to drive the tech forward at a steady pace. For now, hopefully Coinbase and Binance will continue to fight back.
