Could 1 Satoshi (SAT) be worth $1 one day?
That would mean $100,000,000 dollar Bitcoin... but who knows?
Maybe 20 years from now its the reality.
we would be happy if 1 sat = 1 cent. Meaning BTC would be $1,000,000

I love following satoshi price movements...
At that point the question will be what can you buy with a dollar? Hyperinflation will be a reality at that point and one of the most recent examples of this happened in Zimbabwe where you could see banknotes of 100 trillions, if that happened to the US dollar then it is entirely possible that we could see a satoshi be worth way more than that, but at that point using the dollar as a point of reference for the value of bitcoin will be useless and most likely we will use gold or even just think of value and price in terms of bitcoin
