BTC no need to explain, LTC and ETH are my favorites, BNB has recently grown very much and now ranks first in the my portfolio.
BNB recently fell in price to $ 20. And now, many cryptocurrency market experts recommend buying a BNB and selling it up to $ 27.
I supported what you said since the BNB coin seems to be gaining the attention of some crypto investors these days and seize the opportunity of altcoin downtrend by buying BNB for a quick profit its a good decision but this advice is only applicable to crypto traders or investors which have already understand what crypto investment entails or else it better to invest in bitcoin.
