my version is this one:
the bottom line is not a straight line it's a curve
so now i see the bottom at 22 USD
it worked really well for me at the last touch of the line ;-)

That makes sense actually but it isn't really a clear trend.... Drawing this curve afterwards is easy but make it such that it actually predicts the bottom is much, much harder.
If the slope of the curve asymptotically approaches zero it could be possible to hold true. If not it could just become worthless again.
Finally asymptotic laws trend to break down into chaos quite often, especially if they are tested near it's limits...
