The blockchain is a decentralized space; which means that everyone can one way or the other try to create an impact for all of us through the blockchain; starting up a food blockchain may seem ridiculous; but it doesn't mean that it is not achievable. All that is needed to be done as an investor is to follow the progress, process and stated lay plans of the token to see if it can attain success.
If the developers can also work on their marketing; get proper food chain partnership like the McDonald's etc; then the food blockchain could be accepted afterall.
