It sounds like a good idea but how would you get around KYC/AML laws in different countries? In Canada they're very strict so you wouldn't be able to not know who you were dealing with if you were a money exchanger.
Great question!
To avoid KYC/AML laws, we won't be able to allow our users to purchase/sell with domestic fiats such as the Euro, Dollar, etc. It's only coin-to-coin.
We are considering having a feature that allows users to easily move their coins from blockchain to blockchain in a minimal amount of time, to make it difficult, if not nearly impossible for analyses to track. Increasing the entropy of the identity of users of this platform.
