I don't think devs should rush to list BFG top centralized exchanges.  This will likely cause more problems than good. 
Listing costs a certain amount of money and the immediately emerging widespread popularity of the new token can cause a strong influx of users, focused on the dump-pump scheme.  It is better if the token is traded on the sly on a little-known decentralized exchange, which the devs have already promised and fulfilled their promise. 
You just don't have to rush.
