I'm not too sure about the time line. But in my opinion at least until May, how low? I do not know either. What I know is that bad news (even binance) seems to drive the price lower, but good news, has not effect. So given that this is the current trend on fundamentals, I look to TA and see the 200 MA crossing the 50 MA, plus btc's chart looks really bad on ichimoku clouds. But TA only goes so far as to outline what phase of the market is nigh; and can't predict when that will turn.
However, I know the heavy manipulation on btc, and this might be just a ruse to get people to sell off.
