I'm a newbie to trading ETH-based tokens, and I'm completely confused. I'm trying to exchange ETH to BAS and want to be able to exchange BAS back to ETH. BAS recommends My Ether Wallet. I sent some ETH to My Ether Wallet, and I'm completely confused about how to exchange ETH into other tokens. I've added the custom BAS token, but I don't know how to exchange to anything by BTC and REP. They have dozens of tokens listed but there's no way I can see to place an order or post a position. Their help files aren't getting me anywhere and their support pretty much acknowledges that messages fall into a black hole. Please help.
