If we look in the brightier side of it I think that ripple can't make to the top as of now since we all know that bitcoin and eth si popular over the world. Let's just wait that one day ripple can make it to the top.
I doubt ripple can beat bitcoin , Bitcoin is the King of cryptocurrencies. It is the bigger community at cryptocurrency. You should see the bitcoin is still more popular than other crypto.
Ethereum is the second of crypto currency, It is mother of ICO and has integrated to many projects. Ripple has overtake ethereum in past year, But Ethereum bounce back again.
Ripple is still superior and more popular.
So, you can see the CMC now, USDT has overtake the ripple at the third position. Ripple is going down to number fourth.
