Innovation is a river with many streams; the ocean is where our destiny is met with great opportunity. This yet another positive for blockchain and further a leap forward for cryptocurrency trading. Start with what the big guys do, on a small scale very well, that eventually everything is done well at every level.
This is another way people can trade physical goods, services, even "virtualize" retail with ETH BTC LTC, etc trading directly P2P in a secure, stable network. Great work!
