That's not how speculation works.There is a difference in guessing and analyzing.$10,000 this year will make instant millionaires crushing other economical investors.Not in the history of trades such event takes place,be practical.
A growth like that has happened 3 times already in bitcoin - in 2011 and twice in 2013. Now we are in a similar situation - the price was confined to a narrow range - while more and more people have been learning about bitcoin - the result is that any break out will be amplified - just like it has been in the 3 previous occasions.
How big were the jumps ? From $10 to $100 ,$100 to $400 ,yes ! If you can analyse the pattern from $400 to $10,000 does not only seems hypothetical but impossible in such a short period of time which according to OP is 8 more months.
