My guess is: short term trends can only be evaluatet ex-post. But at a certain treshold they have predictive potential for ex-ante evaluation and projektion. Therefor I would only go on the longterm perspective and rely on the green trend line. For the green log trend it needs a big sigma event to breake the trend (say never never) and the only event of this caliber needs (for a liquid market) put-options (with certain clearing house conditions). So I would chill on the green trend, until there are three red flags.

• over evaluation (metcalfe as null-hypothesis)
• exponential or over exponential growth = bubbeling = instability of systems
• the introduction of certain put options (for example by the CME)

timing a low/buy-point with the curent trend is far, far more noisy concept. Maybe it works, maybe it will not work of course if the green trend holds, in hind sight it will kind of work (but this is not better than guessing/gambling)

When you first posted it( the green extrapolition, i think back in 2017), I knew that it is a trend that should hold ...if it will hold, thats a whole nother story.
