The burn is already done? Why is the price keeps dropping then? BNB needs to retrace it's all time high to start surging again but right now I don't see any bullish trend but I believe that 520$ per BNB is still a steal, BCH on the other hand is going to 1000$ wether you like it or not, many people hate BCH but it has what it takes, anyways it's not to late to buy BNB
Usually traders sell up some assets to buy BNB as the burn approaches, anticipating a price pump. Once the burn happens, those traders sell up at a process(thus the dump) and buy up their assets probably bitcoin
