Personally I sometimes look at it that way but most of the time I compare it to FIAT, I cannot deny that.
It’s under to feel this way since at the end of the day we use fiat to purchase everything that we need and not Bitcoin. We need to convert first our Bitcoin to fiat before we can even use it so the fiat value is very important part because it determines the buying power of your 1
BTC.
But if you’re goal is a retirement investment, I guess 1
BTC=1
BTC thinking is easy to understand since you are looking for the future value which is undefined for now.
