Yes, the BNB is growing now, albeit slowly. Burning BNB did not affect the price much, I think a listing of a good IEO will help, there have been no new projects for a long time.
It's not easy to find good projects, you can also see the hype from IEO has begun to decline, so I think even if they can get a good project for IEO, it will not really affect the price movement of BNB
First of all, the promotion of IEO haven't gone down cause it was the crypto investors interest in IEOs that have gone done due to some crypto exchange site not doing their job very but using the IEO platform to enrich their pocket. However, IEO wont be the reason for BNB rice to increase because the trading activities on binance and investors demand level on BNB is what determine the price of binance coin. Mind you, the was purpose to fuel transaction/activities done on binance.
