For now it's only in the concept phase.
The idea is to allocate a portion of the fees accrued from trading on the app and intended for Revenue Share to the Buyback and Burn Program. As the Market Cap is larger than Liquidity, Buyback & Burn may actually have greater positive impact for users (holders) than getting revenues itself. And as so far only esGOOD holders use the revenue share, this will be a good initiative for holders of regular GOOD tokens, thus improving the overall market condition of the project. We all know Buybacks attract new holders - users and project recognition itself.
