It's better if I choose these two coins because these two coins are really very valuable, Cardano has a stronger style in terms of coin development, staking and the newly launched Smart contract, namely Alonzo.
What is certain is that Cardano has a super good value for cryptocurrency because Cardano has a calm, smart and agile CEO, Charles Hoskinson.
Ripple also has a good position, namely a centralized coin supply system that can certainly control the rise and fall of coins, but this tends to be very dangerous because of course there are a lot of #DevelopmentTeam s playing.
