if I personally choose BNB and ETH as well to be my favorite altcoin, because investing in ETH and BNB for the long term definitely doesn't worry me (safer) and of course the price of BNB and ETH will definitely increase very high in the future, so investing in BNB and ETH at this time is very profitable, because when the bullrun occurs, then the price of BNB and ETH will definitely make a new ATH price and give me a big profit.
if things goes wrong, they'd definitely affect BNB performance and it could quite literally lost its value within short amount of time.
