In my view, there will be too many people buying Bitcoin "just for lulz" to justify it going that low. Bitcoin's wide popularity will prevent this. It is more like around $150-200 per coin being the lowest possible price for now. Cheaper than that would quickly lead to a surge in demand for bitcoins, therefore so low prices won't be sustainable.
If you can't open short positions, which is the case if you are a typical Bitcoin hodler, there is no way to earn profits when the price starts to decline. And when such decline is going to turn into something more serious than a ordinary correction, buying Bitcoin in the middle of this inverse rally may be dangerous, leaving you with losses. So not every price movement is advantageous and profitable.
