The core of the app is actually an exchange, I just put out the app right to test the wallets part , so yes an exchange is definitely coming (first release could be within a month) , and yes also I have been thinking of incorporating some simple chat functions in there, but that is not the main focus right now! First step is to get the "market" section running, then work on adding other algos/coins (BTC, LTC, ZEC, and ERC Tokens) .... It's a work in progress ))
