Even if Ripple is legit, I wouldn't buy any right now.
 
Looks like a {Almost} double bottom being formed on 1h chart for BTC/XRP. Just by looking at the price on coinmarketcap, you can see it's already gone parabolic, so it's not really safe to buy at this point, too late. Assuming it's rising under normal market conditions, which I REALLY DOUBT.

One or both the other may happen right now.
1. The house of cards is about to come down, any moment now
2. Bitcoin is going to explode

I am going with number one, and number two.
