It's like... When you go to Chuck-E-Cheese and you buy your tokens to play skeeball, and you get tickets to get your stuffed animals.
in this case, the game tokens pay for storage, and the tickets get redeemed for infrastructure costs.
The liquidity pool (in external capital: HIVE BTC etc) can't "weigh" more than the interal collateral(Larynx, SPK) held for it, and what better place to put it than over the Proof of Access lottery.
There's no Chuck-E in Yurope, did I miss nothing?
Very nice example.
