I can't speak to eMarketChain but I know when it comes to ecommerce and markets within markets they will need to be in strict compliance with all regulations. I've been following a project tangentially related known as FIC Network (creating a fixed income market), and they going through all the hoops to ensure they are abiding with laws so that their token is not a security but rather a utility. In fact, their ICO smart contracts are audited by Blockvis. If eMarketChain has some similar sort of auditing mechanism, that would be very appealing to me.
