from $20 (two pizzas) for 10000 btc
No no no. Going that much back makes no sense. It was completely unreliable territory price-wise.
Markets as we know are just an exercise on price discovery, since its creation bitcoin should have held a very high price but it didn't, even now the price is very low compared to its real value but unfortunately we have to wait for the masses to wake up, as such I agree with your notion that prices back then should be disregarded, if anything I wonder if in 20 or 30 years once the value and the price of bitcoin finally match each other if people will think of bitcoin trading at 60k in the same way in which we think of those 10000 BTC being used to buy two pizzas and will disregard everything which happened before 2021.
