Of course the price will sink, but prior to the listing into big exchange, NPXS was really doing well that's why they were voted and won as the community coin of the month and got listed in Binance for free. If BInance will delist NPXS, that would be a nightmare for investors who are still holding this coin.
Most definitely if they decide to remove its pairs then we can easily expect the price to fall about 20-25% or even more (against $). For me, it would a nightmare because that would result in a second big loss in NPXS for me.
