Binance would de-list it for insufficient trading volume and/or lack of project developments/communications, etc
I guess what's more important for Binance is just the trading volume because it's where they make money and PundiX now is still having a trading volume of over $500K daily, and it's sufficient enough for Binance to make money on the token, maybe if the volume will drop below $100K, then we should consider that as a hint for a possible delisting.
PundiX's trading volume on the Binance exchange is still above $ 100k USD. Binance also didn't issue an announcement to remove pundiX, I think the Pundi X team also doesn't want their coins to be deleted from the Binance Exchange. they will do something.

May be the team was burning a lot of coins and that will decrease the possibility for inflation to happen but remember when we are putting all of our focus into the product.
It must become the main ceoncern.
