What are the advantages that E-commerce proposes to offer compared to other cryptocurrency that are currently already in the market?
I read in the whitepaper that you place yourselves in a comparison/concurrent position to paypal/neteller etc. but I find no mentions of other crypto.

Futhermore how are you planning to prevent abuse of the moneyback system mentioned in the whitepaper? If it's initiated by the buyer without additional checks in place the seller might be placed in a peculiarly vulnarable position(paypal abuse on ebay is a current example that comes to mind).
