Market capitalization is meaningless, even if Ripple managed to overtake Ethereum again in the near future, it doesn't mean that Ripple is more successful than other cryptocurrencies below it. You have to know that the reason why Ripple's market cap is too big even it has lower trading volume than other cryptpcurrency's trading volume is because Ripple has billions of circulating supply. And the formula of computing the market cap is circulating supply times the current price (supply*price=marketcap). So for me market cap is not the only basis of which cryptocurrencies are doing good and has more demands. Will not wonder if XRP will overtake Bitcoin in terms of market cap in the future after they release all of its maximum supply but that would be meaningless.
