Perhaps you should not be in such a hurry to buy BNB, because regardless of the success of Binance, their token will be able to fall in price, because I believe that the current figures are the peak for this coin. Therefore, it is better to wait for the price reduction and invest in BNB at a bargain price.
but if I see how the project that joins the blockchain BEP-2 responds, I think BNB can still continue to grow. there's no harm in buying it. we can also participate in the IEO if we want to have a BNB coin in a binance account, we can get a ticket to participate in the sale of the IEO.
