Until recently, many bitcointalk users were outraged if they started discussing the possibility of replacing Bitcoin with ethereum.  Everything was explained by the unreality of this situation, as if Bitcoin and Ethereum have different roles in the cryptocurrency market and their functions will never overlap.  But the situation has changed and we see a completely different reality.  But in relation to BNB and Ethereum, in my opinion, it can be said accurately and without any doubt that BNB and ETH are really created for different functions in the cryptocurrency market and therefore it makes no sense to compare them.  BNB will never replace Ethereum in the first place due to the fact that Ethereum is already a full-fledged coin with its own blockchain and at the same time is a promising platform for smart smart contacts.
