In my opinion, will reach to $40k, however, may go down to $15k after July 2018.
I believe that 2018 has been a very trying time for Bitcoins and it has indeed separated the serious investors and those who just joined the bandwagon because they seek to get rich soon and I think in the end it will be great for everyone in the crypto currency community And make the currency more stable than it used to be with all the glory and profit hunters.
