In 2014-3-30, the exponential trendline model gave a buy signal at $460 and the price has been unable to go below it for any extended time even after 4 weeks.
In 2013-11-23 it gave a sell signal at $872 (SlipperySlope's 0.40 confidence) or 2013-11-28 at $1,056 (my 0.45 confidence). It was also unable to stay above it for any extended time.
What odds do you want? As I would be betting to win less valuable coin, you shouldn't get much better than 50%.
I think you will offer an unreasonable bet so that you don't have to make one at all.
But let me know.
