I'm wondering what could've lead Binance Coin towards new heights within such a short amount of time? Does the "De-Fi" hype have to do anything about this? Do you think BNB's current prices are sustainable or not? Your input will be greatly appreciated. Thanks. 
It doesn't, the crazy fees on ethereum could be the main reason that drives the price of BNB to touch a new ATH. There are some news that said some projects on ethereum like curve is starting to consider Binance as a place to migrate its protocol. This will bring the BNB chain the new users. We know that if curve has a lot of supporters and it could be a disadvantage for ethereum. The fees are the only reason why people starting to adopt bitcoin.
