Good for Huobi for trying to compete with Binance; though as of now I don't think Huobi is even close to beating Binance. Binance is just simply doing everything right(as of now, at least). I honestly really don't see an exchange beating Binance soon. They can try though, competition is always good.
You mean running away from Japan just two days after going public and declaring there is nothing wrong with their licence?
