SBD went up to like 8 USD recently. Is there stopping that from happening to HBD? Realistically if it is tradable on other markets, and those other markets have more trade volume than the internal market, then what is the point of stabilizing the internal market mechanics if external is more of a driving force?

Genuinely curious, I have no idea what the point of HBD is for tbh. Seems like there is no actual need for it. Does it do something very important? We have plenty of decentralized exchanges, why even have an internal market at all?
