Maybe this is the same fight between XRP and ETH. XRP is capable of being two coin numbers after BTC. But that did not last long because ETH returned to number two. Because ETH has increased its selling value.
I think its not the value on why xrp surpass eth because if we can see the price of xrp is only small . Xrp and eth are not really a good competitor because we can obviously tell that eth is the winner . Eth has a lot of uses but xrp is too common . Meanwhile , waves and eth are a more better competitor because both coins have the same feature both so far eth still takes the lead. We wont know maybe waves can make a comeback in the future .
