I think it's gonna be 10$.There'll be a lot of money going intro crypto until we reach 2019.Last year in april XRP was 0.03$, if i would've told anyone that it could get to 3$ they would've laughed at me.
Unless, whole market cap goes to $4 trillion, it is less likely to see ripple at $10. There should be a very important news that pump ripple beside the effect of increasing whole market cap.
The increasing whole market cap depends on how people buy and hold their xrp, and if the pump continues to happen that speculated price will be achieve. For now its so hard to tell how predictions will go throughout, because the market was so dependent on how bitcoin increases day by day. Many trader were on close monitor with each and every coins, that's why we don't seem to any progress with other currencies aside from xrp.
