Is Ethereum second?
If so wich Cryptocurrency Will be third, 4th. 5th.??
What You think wich coins are competing with Ethereum?
I Think Ethereum and Bitcoin are number one!
3rd. I Think its a BCH.
If you look at the rankings on the coin market, of course BTC number 1 and ETH number 2.In Q1 2019 XRP had risen to rank 2 in CMC,I conclude that the rating on the CMC can change immediately if the coin is declining in volume, of course it will be rivaled by Coin which is growing in volume.
