The common theme in most of the replies is that the coin is centralized and nobody actually knows how much does Binance hold but it's a large percentage, and i should trust binance to do the right thing and that they won't dump too hard.
My conclusion is that BNB is too centerlized and that means that any whale would think twice before investing in BNB, which negativly effects the price long term. that suggests to me that the success of BNB is directly linked to how successful Binance is.
