I have found examining the extremes of things can be illuminating. Sometimes that involves suspending reality temporarily in order to examine the hypothetical, that is ok we can turn reality back on :-).
So the value of the Bitcoin is driven by supply had demand. There is a fixed number of bitcoins that can be mined. 21 million ??
Likely 3.7 million are “lost forever” ( I understand your explanation but I’m typing on phone), so that is 18% of the total. The ways they get lost continue, so what does the lost portion do to the value each ?? What about when it is 36%, 50% ??
Supply and demand says price will rise ??
