I've seen these BSC Memecoin projects try to get Volume and Hype through lowering the transaction taxes for an hour or two. Kind of like Happy hour.
Also when I used to be heavily involved in these BSC projects, it was a must to get listings on these token sites like top100token.com and such. That brings opportunistic gamblers into the token, who are honestly buying a little bit of literally everything on these sites.
I did it about 2 years ago so I can't remember more sites on the top off my head, but I used this one the most.
Just go there and click "Submit coin", fill in the details and it will be automatically listed as a new coin and later with either upvotes or the staff accepting the token to the official listing.
