Theoretically you are correct, if you consider the high volatility of bitcoin it can drop that low, but in reality you not. This is overthinking or over analyzing things, though bitcoin has a high volatility, a lot of investors had already minimized their risks and people will not let their investments to go that low, probably you might have just thought that because of the volatility it can go down that much, but you failed to consider reality vs theory, and the reality is, bitcoin will just have corrections but will not crash.
I totally agree, it can even happen that it could drop to $0 each and there's nothing we can do to revive it, but there is totally a greater chance that it could go up to the moon. Bitcoin code is solid and there is little factors that can affect the price to drop down to even $2,000. Probably the only things I can think off that would bring the price down to that is when all governments ban bitcoins, they find a bug to it and ultimately create unlimited bitcoins or alter previous transactions, or just down right be able to hack any address or even create transactions out of thin air. All of which have a pretty low probability to happen.
