Yeah, that's right. BNB has overtaken both DOT and ADA in terms of market capitalization. I think this is largely due to the many projects and users/traders/investors migrating to the Binance Smart Chain.
Not just you mate, there was a time I felt bnb at $30 was over bought, so I had to panicked and sold mine, bnb took the whole crypto market by surprise, I guess the demand for bnb increased shortly after project running on Ethereum started migrating over to binance smart chain (BSC) due to the insane gas fee on eth network, if the problem with eth gas fees isn't fixed soon bnb might just over it also, at least no insane gas fee on Binance Smart Chain.
