A Bitcoin worth $68K 2021 could be higher than a Bitcoin worth $77K today
and many tend not to think about it Same applies to other assets.
We tend to focus on nominal value and neglect real value
If we are to measure and account for inflation Bitcoin price would be lower than we see.
Bitcoin or whatsoever potential assets projected to hedge against inflations and to estimate the value of the asset as bitcoin, it must be evaluated according to its real world value and then you'll see that what the asset or bitcoin was worth in the previous based on the economy ratio isn't the same because of inflations.
As the matter of fact that the fiats can be devalued by inflations, you'll also see that the lower price of the asset as evaluated in the Usd at the past has stronger economy value in the global market than the high price of today's.
So the values are only affecting the fiats while the asset price increases to sustain the inflations.
This reason is why it's important to invest on potential long term assets like bitcoin.
Of course 1 Btc remains 1 Btc while the value is evaluated according to the real world price measured in Usd.
