As long as the price is still affordable to buy it and not too expensive, in my opinion it is valid because BNB is also the third best altcoin on the Crypto market, so there is no need to hesitate to buy it because the community and investors behind BNB are very strong, plus the Binance market is also  the largest market so, very confident that if you invest with BNB, it seems that now it's not too late to buy it..
