It looks like some big players have got themselves involved with BNB. Until 2-3 months back, the daily volumes used to be in the range of $25 to $30 million. This has increased by 10 times, to $250-300 million. There have been a sharp increase during the first two weeks of this month. Anyway, for me it looks quite suspicious that this coin could rise by 170%, despite the fact that Binance underwent a major hack. It is quite possible that the exchange is pumping its funds in to BNB, to give a feeling that everything is going well.
