POT
POTs can't be used outside of the protocol for example in DEXes. Once NPM token is launched, it will replace POTs. For now, Neptune Mutual team and a few others will have access to POTs. POTs aren't conventional ERC-20 tokens; they can't be transferred freely; they don't have any value, and therefore must not be purchased or sold. Agan, POTs are distributed to individuals and companies who particpate in our governance and dispute management portals.
