Silver gains in history.

I was looking at some charts on Kitco. I noticed that in 10 years silver went up on average 20% a year based on the previous years price.
This year alone it has gone up 100% or 2 x the starting price.
With this being said, what future does silver have? Will it double again in the years to follow or go back to the 20% a year gain that took place over the last 10 years?
I know very little about the market trends, what all is involved in manipulation, and all the other things involved in the market ( PM's and stocks ) that is talked about vastly on this forum. The MH - SOM debate is WAY over my head.
I just wanted to see what ya'lls thoughts were on this.
