5 years is a long time, maybe the price will fall, or it will enjoy the support of crypto enthusiast. I don't understand though what do you mean by discount? As far as I know, they have this sort of quarterly burning of it's token, so that alone might push the price in the future, but still we can't really tell at this point.
Currently, it's worth ~$40 million, so that's a lot of money already, so if in the next 5 years, Binance remain on top of the crypto exchange competition, maybe just maybe it will grow.
