Serious question: under what legal theory (not loose analogy) is the BCH corresponding to a wallet held by Coinbase property of Coinbase's users and not Coinbase?
That's hardly specific.

There's a reason I specifically excluded loose analogies.

And the specific rules that specifically apply to a fork of a cryptocurrnecy and a firm providing wallet services like Coinbase are...what, precisely?
Perhaps general securities laws are written in a way which encompasses this scenario, but I'm asking about the specific applicable laws that cover the situation at hand.
