bitcoin and crypto have long since parted ways, they are different things now. even from a regulatory perspective bitcoin is the only one that has clarity being defined as a commodity and not a security, everything else is in a grey area
BTC has the best legal argument for being treated as a commodity, but there has been no legislative decision on this.
The CTFC sees BTC and ETH as commodities. Gensler pre-SEC said BTC, ETC, and LTC are commodities. The SEC and Gensler post-SEC says they are all securities, except maybe BTC.
The Ripple decision (Yesterday) says that unless a crypto is contractually sold to an investor (e.g. not directly listed via an exchange) then its doesn't fall under the Howey test.
