To the maximum it can go till the bottom value of $350, not less, because the price of bitcoin started from the value around 350$ - 375$.
350$ is very less amount. I cant see its going anywhere below 400 Dollars either.
Maybe after halving, it can go to $200 , if it has a lot of pressure of selling all and buying none.
This will come to the market when the price is too high and some traders think that it wont go any on that current price.
