They destroy BNB every 3 months reducing the amount of it and there still many reason why BNB will be easy to hit that price.
BSC was increasing its gas price, I think it's because there are many projects in BSC that causes much more investment to the platform and because of burning that will reduce the total supply, I think the price of $1000 will be very easy, because Ethereum is not fixing its expensive gas price so BSC will still relevant because it's a lot cheaper than Ethereum. I think, BNB will eventually have the price that ETH currently has because BNB will have lower total supply if it keeps burning the BNB, this means the price of $1000 is very realistic in the future. After all the NFT hype will help BNB too.
