If they keep launching more IEOs and if those IEOs keeps giving us those awesome profits then I am sure that the price of BNB will keep on increasing both against BTC and USD. (IMO)
whether later when BNB prices continue to rise has no effect on their exchange platform? I don't think the exchange coins that are too expensive are too good. there must be control from the developer for this, BNB prices cannot continue to rise, there will be a negative effect on their exchange later.
Why do you think that there will be a negative effect if the price keeps increasing? I invested in BNB at a really low price and I am really happy about the price. With BNB burn I think the price should go a bit higher now.
