You are a good writer and convincing; I give you that. 
 
I can honestly see it going down like that, as that would be the unthinkable ($100 bitcoin and a collapsed market) only to soar back up again in 2016. 
 
Here's my plan: I'm gonna buy my favorite alt-coin.  Then I'm gonna buy some more.  And if the price goes down, I will buy even more.  And no matter what, I won't sell an asset I believe in just because the price drops. 
 
As a long term trader who doesn't want to play the swings: once your money goes into an economy, it stays there.  If you aren't willing to buy an alt-coin for 3 years, don't buy it at all.
