Well let's see, I transfer value around as bitshares (someone wanted to get paid partly in bts), I have bought and sold bts, btc and a handful of user created assets such as brics. I'm also using the openledger dex for holding my Qora as I couldn't get their wallet to work. So, you can use it as a wallet, (you control your keys), and you can trade dozens of coins and assets in a de-centralized manner. I believe you can change the colour to something else. Never bothered with that, I don't mind the black.
