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.
I think after bitcoin has reach its peak when the halving it over it will be down for 200-300 dollar then that will be the new price.
