It it purely based on sentiment, I admit I am not basing this opinion on any TA.
Ripple has a pretty good real world application for settlement and remittance systems with all the benefits of the public ledger technology. The vision of the project is pretty clear and a good candidate for the early adoption and implementation in real life of the blockchain technology in general: this is a pretty basic use of the technology yet an application I can see happen in the real world.
It has partnered with a good number of banks and financial institutions already and is also experimenting with a good number of actors including CBA and ANZ here locally.
In these aspects, Ripple is a promising and solid project IMO.
Then when I look at the chart, say the 3m one, XRP hasn't been doing much unlike its peers in the top 5 or top 10.
Now, maybe it won't have a break out, and perhaps it'll keep stagnating or even go down, but it often happens that after a prolonged period of boringness in a coin, interest picks up and boom.
Also interesting to see the Koreans have consistently been making the largest portion - by far - of the buying, unlike other coins like ETH or LTC.
Only my opinion of course, could be completely wrong - do your own research.
