Cardano all the way. Ripple could become obsolete when Wanchain shows its claws. On the other hand, in my opinion Cardano is still over-valuated at this point, of course not as much as at the ATH but still.
I think cardano price is cheaper than ripple, if you invest the same capital it will get more coins if we buy it on cardano. and chances are we'll get a bog profit as well
