Yes because they are so excited to sell their bitcoin right a way if bitcoin reach that predicted value. But i think it will not stay for a while on its value. it will fall again immediately because its always volatile when bitcoin reach in a higher even before. Because of some reason from market.but after that falling moment it rise again maybe it will reach into 6k in this up coming year 2018. As of now we need to check it every days to assure that we can sell our bitcoin in a right time and also to earn much profit .
