How could you not believe in ripple but not as much as you do believe in BNB? Ripple seems good in early days after it has entered into the market but as per the time passes we have got so many good coins and that's why it is not preferred to ripple because investors have dozens of options which are more likely better than ripple.
There are many to choose but only few is worth having, I have BTC and ETH to focus with in holding, but different altcoins to do trading with, it's not necessary now to have many coins but what we need is those consisprove that they still developing, In case with ripple, it is one of those I used more in doing transactions in casinos or exchanges to cashout since its lower in fees,but I don't mind holding it long since it's better for transactions.
