I like the idea. Is it going to be like Etherdelta though ? . I love trading on that but it can get confusing at first and the site is SLOW.
Etherdelta is a stock exchange with large commissions. Decentralized exchanges on the ETH platform cause huge damage to the coin due to the large number of transactions. Developers try to fix this, they will implement 3D blocking technology(sharding), but so far it has not been implemented.
