Speculation and gambling is just complicated casting lots.

Predatory gambling where the participant can only win good feelings and lose money, is the immoral, addictive nightmare nobody wants. When talking about regular joes anyway. Be honest enough to sell good feelings straight.

I can't comment on the select finance bros who have manipulated the rules towards a specified outcome. Not really casting lots anymore at that point.

If it gets too corrupt all bets will be off, and that will hurt everyone who needs short term liquidity and to take speculative moon shots.
