$2000 sounds too low. If the rise will continue, it would hit around $2500-3000 at the end of they year. Maybe even more, depending on the news. But crash may also happen, to $800-1200 for example. But I think there's much more chances that uptrend will continue in 2017.
Do you seriously think that we will see downward crash do severe to see $800 or less? It would have to be something really drastic to bring down value of BTC by 50%.
At this point I can't imagine what that would be. So I expect only standard price corrections to happen from no on - no higher than 15%
$2000 will be reached sooner that later, definitely before the end of the year. I bet after Australia will regulate bitcoin in July, we will see $2k.
