Now what I don't understand from OP is how he can make a linear connection between two different time eras which had a period of double exponential increase inbetween them.
His lines are only based on two points, two points can always be connected by a straight line.
However the lines are pretty much useless because at the start of the graph the value does not even come close to either line, while later the price is much below the lines, after which it overshoots the line by a huge margin, after which it reaches the end point of the line which is of course aligning because the lines were based on that point in the first place.
So the lines are just that, lines, nothing more.
