We already are on exchanges:

- Mercatox
- Bitgrail (written from 0 for XRB)

Honestly, go on bigger exchange won't change things in my point of view.

I see this road actually for the coin:

- some node improvements
- light wallet for mobile and desktop
- at least a company which provide PoW on demand asking a little fee
- more adoption by serivces, and so more nodes.
