I would divide my deposit for two parts and buy both just because in total ETH and Ripple will bring you more profit then BTC when it stabilize. Even when BTC now shows the percent of grow, altcoins give double..
Yes, we make more profit through ripple but chances increasing price is very less compared to Ethereum, compare to the supply of both these coins. We have to compare both the charts how much profits both coins has given to the investors.
