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.
The records state the position of each coins according to it's market cap, Bitcoin and ETH still holds the number 1 and 2 spot consecutively, we seen both bch and xrp able to snatch the place from ETH but afterwards the coin regained it's place. We do have a tough judgement picking what coin to be next in line, but things should be decided with how the coin performed and what addition it can bring inside the industry.
