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.
But usually we can not predict the market of bitcoin trading. Because some buyer will come with huge buying pressures like buying for some million dollars worth of Bitcoins.
