It was my impression that any coin could be listed on certain exchanges if you pay the fee to do so. Depending on the exchange it could range from 50k to 1 million USD just to be added.
Yes, that's usually about right for most exchanges. But if your coin isn't popular enough, they usually will not add it.
However, there is a protocol for decentralized exchanged called 0x. Any tokens on Ethereum can be traded on this protocol, using websites like Radar Relay.
