If they would continue to pump in new features, then yes. But I am afraid we would come to the point when Binance would not have any new ideas and all altcoins that migrated to BNB chain will drop as well as the main asset.
New ideas are just to establish new businesses that will setup a standard to continue making the value high in future. Once you have a standard products already established, you dint need much new ideas again until maybe later in future. Binance has already laid down lots of strategies that will enable continuity of their Binance coin, and will sustain it not to make investors dump it very soon.
Look at some projects in the top 10 in coinmarketcap, how many products do they really have and they are being sustained, talk less of Binance that has produce several products that are very useful to the society on a daily basis, they have trading exchange, IEO platform, margin trade, and few other products that will continue to invite and attract new investors and users.
