1 BTC = 1 BTC
or is it
1 BTC == 1 BTC
?
technically the first statement is not a boolean.
but the second statement is TRUE .

..but if you compare strings you have to use quotes

"1 BTC" == "1 BTC"
Put this way,
"1 BTC" = "1 BTC"
would just raise an error, right?
Well I guess a variable of "1 BTC" could recursively store itself and then lead to an "OutOfMemory" situation.

Can't we just introduce something like "in 2015 Bitcoin" as deflation adjustment, just like dollars have a inflation adjusted way of saying "in 1980 dollars"?
So:
$1 in 1980 is equivalent in purchasing power to about $3.19 today becomes: 1
BTC on January 1st 2012 is equivalent in purchasing power to about 0.00008976
BTC now.
According to my simple calculations, I get to some different results:
While 1 Dollar in Jan 2012 has the same purchasing Power than 1.13 Dollars in Feb2021,1 Bitcoin in Jan2012 has the same purchasing power than 0.000124927228676061 Bitcoin in Feb2021.
