Npxs token will migrate to pundix token with denomination 1000:1 to reduce the total supply. I don't know if the price drop is the reason they do swap.
Sometimes reducing total supply of the token can help the price, but no guarantee. The most important thing will drive the value is the platform (business plan) it self, not the token specifications.
