Think it would be best for the team to hold off on listing on any bigger exchange till bounty tokens are absolved first - or list on Yobit. With the product release far out - early 2019 - don't think the team will be focused on marketing just yet. No point going big if there's no marketing behind it
Interesting, why would you postpone listing on a bigger exchange? There are lots of coins in POC/early stage listed on major exchanges, and they perform well. Certainly, the marketing will be needed but in can go simultaneously with coin listing.
