Compared with eth, dash and XRP, the value of eth must be the highest. The decline of eth is the smallest in terms of its current decline, and in terms of value, eth ranks second only to BTC.
I agree, eth has more potential in the market advantage, where last year we all know own eth prices also rise rapidly. but the 2 coins that lin also has the potential and interest of a good market, just the name is not as famous as eth now.
Investment wise, Most of us will choose ETH but for risk takers, xrp might also considerable, as they new being centralized and the media hype with linking banks support will be a good game for pumpers, whales also present when they smell some opportunities, the value of xrp still cheap against ETH and dash,
in the end, it's still depend on how or what type of investors/traders are we when looking for coins to support.
