For the use case and about exchange site,
I suggest not yet starting with easy exchanging pob to other currency whether Fiat or crypto because panic sellers will take advantage of this and sell off all thier pob. So creating a exchange site for exchanging one cryptocurrency to the other like normal exchange side like binance another popular exchange sites and collecting pob as a transaction fee a very cheat charges. Rewarding people who hold pob and linking the site to proofofbrain to earn pob. That is the secret strategy of every popular exchange sites they used to promote their own crypto.
Binance used it to promote BNB.
THAT IS A GREAT STRATEGY OF USE-CASE I SUGGEST. USING POB AS CHARGE IN EXCHANGE IN CRYPTO TO OTHER CRYPTO AND POB AS CHARGESTo @leprechaun,@scholaris.pob and @proofofbrainio

Exchanging pob to other cryptocurrency should require charges or transaction fee for each transaction to help you in liquidity. And the best way of collecting transaction fee is collecting pob as charges not in USD or other cryptocurrency.
