It is no longer news that Binance is launching their own chain on the 23rd of April, 2019. All BNB holders can convert their ERC 20 to Binance Chain and MITH has announce to be the first to migrate to Binance Chain and pumped 60% overnight. Is Binance Chain decentralized or semi-decentrilized considering that they will be in control of their chain network. With the lack of smart contract, are they really pulling any challenge to ETH? Well. If the purpose is for crowdfunding and the possibility of getting listed, BNB might receive a lot of attention. In my own opinion, Binance Team is setting the pace for other exchanges and they are doing really well.
I don't think that Binance Chain is a threat to Ethereum, because there are many of the people here in crypto world that Ethereum will surpass by XRP, BCH, BTG and more and yet Ethereum was still remain stable in the market. And besides, in some other businesses in the entire world that Ethereum was being accepted as mode of payment for some merchants.
