Yep, you are correct, since Ethereum mainnet has been clogged and many investors are complaining, projects might switch to Binance Smart Chain and this could spell doom for Ethereum although it has surpassed and reach their new all time high this year. But if sustainability will be their main stumbling block, then it will be Binance advantage as we have seen it has grown tremendously in the last couple of weeks.
This is interesting, ethereum for a long time it did not had competitors that were as powerful as it is and it could get away with the high fees simply because project developers did not had an option but now they have a huge competitor in binance that is going nowhere and I will not be surprised if it could eventually take ethereum’s place as the second biggest coin in the market, it is still far away and it will need to make a 4x from its current price but the potential for such movement is finally there.
