Ripple could never dethrone bitcoin. Price wise, by just comparing their total supply, it could never exceed bitcoin's achievement. And with the community bitcoin is having, bitcoin will continue its reign over other cryptocurrencies.
have the greatest value on the market don't necessarily make any coin a king, Bitcoin is the actual king because of its utility and the daily volume as well as the trust of the people who use cryptocurrency, I don't take away the epothesis that one days Bitcoin will be dethroned, but one thing is sure; it is not going to be from a coin/token that are currently on the market because they have added nothing for the altcoin but contrary ; at each devlopement of a coin people recognize the power of BTC and it becomes more and more powerful.
