I think the price could exceed 2000USD at the end of 2017. because of the demand for more and more so that the price of bitcoin will experience a very significant increase. as well as the growing number of e-commerce makes bitcoin increasingly demand a lot of people in this world.
$2000 seems to be possible if calculated based upon the ongoing price variation. Growing ecommerce is a supportive thing for digitalization. Recently the price have been experiencing good increase. By the year end lets hope for $2k.
