Alternative Currencies that might reach 10 dollars next year are NXT, Ripple, and STEEM, which shows stable amount and growth (even it is so slow).
You think Ripple could reach 10$ ? Are you sure ? that means a total market cap of more than 380 Billions , ~40-45% more than Bitcoin market cap.
I agree with your opinion. I highly doubt that Ripple would ever reach 10$ anytime in the near future. I am expecting Ripple to reach 2$ by this time next year. I still don't want to invest in this coin since a major portion of the coins are held by the developers who are freely manipulating the market to their liking which is not something I prefer. I prefer Stellar Lumens a lot more in this scenario.
