Well actually BNB now is around $558 and most likely it could even reach more than that. I’ve also read this’ll be an “ETH killer” and could take over ETH too, maybe it’ll even reach $1k before the next coin burn.
Most likely bnb will hit $1000 before year end, and as for being an 'eth killer' i don't think so, i believe this ecosystem is big enough for both binancesmartchain, ethereum, polkadot, cardano, tronix or any other network to strive successfully, it is about finding the best service that suit your needs as a developer or as a firm, institution or what have you,
It is always good to have a competitive market, this way there won't be monoply of any particular project, with so many network to choose from, it is upto the owners to work hard to make their network stand out and attract more users.
