The two coins you have in your portfolio are a very good choice for the long term, although at the moment both coins may experience a slight drop in price during the current bear market, but in the long run there is no doubt about these two coins as they have proven capable of delivering great returns especially for long term holders.
If you are interested in investing some of your funds with altcoins when market conditions are bearish, then BNB is certainly one of the coins worth holding.
