The returns on staking do come from new investors. As you point out in your next comment, they turn negative after the project stops growing.

I agree it's not a Ponzi scheme in the narrow sense that some mountebank is telling stakers that they're being paid from the profit of nonexistent businesses before running off with the money. But the dynamics are identical: as you point out in the next post, the project depends on stakers earning rewards from its growth and the scheme collapses when the project stops growing and the stakers seek to avoid losses.

The dynamics of a casino are different: it doesn't promise its gamblers a positive return and thus doesn't needs constant capital injections to survive. Gamblers are service consumers, not investors and betting for entertainment that the wheel will stop on black, not for profit on the casino's ability not to default.
