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.
I think most of crypto users are agree that Ethereum is the second. 1st Bitcoin, 2nd Ethereum. About the 3rd, it's hard to choice, there are so many good altcoins like BCH, LTC, XRP, BNB and else to get the spot for 3rd but if we compared them all with the market cap then XRP will be the 3rd.
