I think you've picked a starting point a year into COVID? ~$7500 (Dec 2019) to ~$35000 (May 2022) https://i.imgur.com/N117Uqp.png
In my timeline 2018 happened before covid hit. You can even see it on your chart. How is the late-2019 starting point relevant?
Because it was right before COVID occured and pretty close to the average trading price for the prevous 5 or so years. Sure, the price has run significantly higher than that average for a month or two among those 5 years... If I wanted to be pedantically accurate, I would have added a few paragraphs of disclaimers, but it was an off-hand comment pointing out the obvious that the GP had ignored in their own off-hand comment.
