What drew me into cryptocurrency was its decentralization. So I can't get behind Ripple. I am not really all that into Ethereum either, so it's kind of a lose sandwich for me, haha. I can't really say that I'm going to dump my life savings into DogeCoin either though, so for right now, my main focus is on building my Steem account and acquiring as much Steem as possible. As it is one of the few cryptos that you can actually really earn without much investment.
(If I had to pick a winner though, I think Ripple is going to win out. Not just because it feels more stable to the seemingly easily rattled crypto-community, but because I think Ethereum is in a bubble and will pop. Ultimately I think cryptocurrency in general is in a giant, ready-to-pop bubble to the likes of the 2008 meltdown, but Ethereum specifically is riding on the wave of its popular games, ie crypto-kitties and puppies and the like have all hyper-inflated the value of Eth. So, just like Beanie Babies, when the fads dies down, I think the share values will plummet.) I am by no means an expert on crypto though, or trading, etc. but that is my educated guess! We shall see!
