I like the concept of bringing the commodity market on blockchain, i myself do online selling before and vice versa.
the rating system is a huge plus for me it instantly gives a hint and develops trust on both sides,
when trading online trust and good service is really an issue.
Im excited about this because its also one way of spreading awareness of the cryptomarket as well and the blockchain technology too.
though there are many issues to solve first on the list is the traffic on the blockchain.
