The fact that Huobi is a Beyond Protocol investor is a sign that BP will be available on Huobi sooner or later, I think it's just a matter of time. If we look at which exchanges the official BP Twitter account follows, we can see that they follow Gate.io and KuCoin, it may not be a determining fact, but it can give us some clues about the exchanges to which the BP team submits proposals. For those wondering "when Binance" have to wait for BP to have its own mainnet.
