for bitcoin to be worth more than 40k, it specifically needs to be explained to many especially those who are not really interested in learning. Otherwise it will not get widespread adoption.
Bitcoin is (with the big B, although lately I've been using Bitcoin when bitcoin would suffice) is a complex asset
I only responded to Frederick's post re: "solving puzzles, consuming energy". For everything else wrt Bitcoin, I can point to books
There are many detailed videos on bitcoin mining and the reasons, incentive mechanisms, going back to the Bitcoin whitepaper, but I did not post those YouTube videos because US Treasury Secretary Janet Yellen video explained it very well
For anyone not interested in learning and as you say prevent widespread adoption, I will have to disagree. Bitcoin has been doing quite well with the adoption and there will be people left behind
Bitcoin will continue to be successful
