Yes and no. Gold isn’t a security, for instance. Unfortunately (for coinbase) ICOs and related grifts pretty clearly meet both the spirit and the letter of the SEC’s definition.
I don't think that if you were to make an exchange that made it easy to trade physical gold (rather than deriviatives) the SEC would suddenly determine that gold was a security.
ie: BTC, LTC, Monero are gold but an ERC20 token is a security and Cardano is a security because it was an ICO? I don't know off hand if Ethereum was an ICO.
I keep thinking this but I can't remember seeing anyone suggest that each coin could be categorized differently. Is it possible we ended up splitting the crypto currency market into multiple groups?
What is WETH then?
