I think we will see more than $ 1k for BNB, because the cryptocurrency is still not at its peak yet.
The NFT platform can also push this coin to a new level.
There's no peak for a coin that has only a limited supply, in the long run as BNB gets develops more, the demand will increase hence the price will rise. Think of that as a possibility as Binance is composed of a good team that continues to develop the project to reach its ultimate goal.
If ETH with a lot of complaints reaches $4k, BNB should not be far from achieving it since it's a way better coin than ETH at the current status.
