I don't believe that bitcoin can go down in $2k range as the support is looking good and also there aren't any FUD recently which cloud cause further loss of marketcap of bitcoin. I also am speculating that the price will be in the same range in which it is as of right now until the next segwit lock down or it can also increase if any news comes up favouring bitcoins. So best bet would be to either buy right now in this range or wait and hold on to whatever you have till next price movement, as the next pump will be bigger than any pervious pumps and will cause bitcoin to rise to new all time high.
