As long as you bought it at dip it will always be a good buy. Try to divide your investment like buying 1/4 of the total funds when there is price drop and another 1/4 when it continue to drop. I think from that method you will surely make a profit. BNB is a good exchange coin but yeah we will always accept the fact that BNB will remain a reputable Altcoin. The best thing to do for now is to buy and hold for future purposes.
