This is causing major turmoil on the markets, but all of that is based on fear. If investors were rational, they'd realise that (1) This news does not affect bitcoin, litecoin, IOTA, Monero and the like, only blockchains that allow creation of tokes, and (2) this news means that old ICOs are effectively grandfathered, and it's simply going to be much harder to create new ICOs. Which, in turn, means that there will be less competition for existing tokens, which should drive the price up, not down.
I don't know about you, but I'm going to buy the dip.
