Ok, so why did XRP suddenly hit $3 (and above) in 2017 and went down? I would go with the theory saying that it reached high because banks and businesses shared their positive feedback about XRP. However, the actual adoption and the further domino effect might take 5 to 10 years, but it will (since XRP has already proved to be a reliable tool for cheaper and faster global transactions that can be effectively used by big enterprises). The question is when and how fast they will adopt the new xCurrent framework that takes the process to the next step. Once they do, the domino effect cannot be avoided and the price will hit even above $10. The question is when and how fast. That's why I am pushing for XRP being a long-term investment option now.
I dont think XRP or ripple will be able to achieve that amoun in 2018 because the only thing that XRP's has pumped last time is because they spread FUDs from a fake partnership if im not mistaken,but people dump this coin after Binance has announce that they wont accept XRP in their exchange,people dumped this coin after that announcement which is good because most of the investors come back to ethereum's market which is in that time is only top 3 crpyocurrency in the coinmarketcap.
