Not many people know about the listing on Probit because it was no active advertizing campaign. Also it is necessary to promote BNF on Probit exchange and add new listings.
I think if just to make people to know this token already listed on Probit, campaign will not needed. Pin it on social media accounts, on telegram group and post it in the ann thread in bold I think is enough, people will see it easily.
If the dev really want to promote BNF on Probit, then an event like trading competition might something suitable to hold. It will also increase trading volume on Probit.
