Ripple's price action is far more reliant on the South Korea market than other cryptocurrencies. South Korea obviously took a bit of hit when the government regulated the exchanges/banks. When you factor in South Korea and a general market softening you can see why the price has been stagnating.
Another positive price catalyst will be the launch of the SBI Exchange that will use XRP as the base trading pair. This should significantly increase XRP volume and help de-couple from the XRP/BTC pairing.
I feel that while the price of XRP has been moving sideways, the intrinsic value of XRP has increased substantially with these announcements. Once the next run up is established I believe the price will start to reflect the previously announced partnerships/pilots.
Disclosure: These are my personal views and not investment advice. I am a XRP holder.
