Binance draws other projects from the Ethereum network into the blockchain Binance,
Ethereum needs its own powerful stock exchange.
I read a bit about their blockchain, but i don't think it can compete really, at least not now. Maybe somebody will chose it over ethereum if they throw in a free listing on their exchange?
i see alot of project migrating to the binance chain lately i feel they are making the right choice considering the way binance is fast growing and evolving, honestly i wouldn't take anything away from binance ability to compete with eth network, this is a fast growing company that is really doing well in the exchange market, there is much choice for project to make now regarding which network will be favorable to lunch their project.
but in this case like Sirius where they already have their own chain they cannot really have any benefit from it, it's just an advantage for trading purposes at the moment and make sense just for projects which are token based
