At the moment you can invest in ETH and XRP. I don't understand why you're putting competition between these two coins. These coins are very promising cryptocurrencies and I have invested in both.
I remember everybody was in a panic a year ago: people were buying a lot of Ripple at $1. And where are they? It's a very deceptive market! I think we'd better wait at least 6 months and see whether Ripple's worth buying
