I used to ponder, what if 1 BTC became worth more than 100 million... what do we do with the satoshi, divide it further? Similarly, if you think about any BTC in terms of purchasing power only, and not in comparison to USD or fiat, what happens when the purchasing power is so high that 1 satoshi grows past the value of even small insignificant items..like a candy bar or a bottle of water or bag of chips from a snack machine..like if 1 sat becomes too much purchasing power for anything at all no matter how small...
