i would claim this for the erc20 token offerings that are securities, but not for bitcoin, specifically. bitcoin, being decentralized, is literally the opposite of what we traditionally call a "stock". its an asset, and a growth asset to boot. but stock represent singular entities, the corp that issues it. bitcoin is a consensus; bitcoin price simply reflects what we collectively want it to be.
some of the alts that are securities might fit this bill. even some of the better, more useful tokens. but bitcoin, specifically, has to sit this designation out.
Its Brian Armstrong, so I will give him a pass
but this statement bears a bit more consideration, imo.
at least he isnt a wallstreet bald head calling bitcoin a fraud
