I'd say it would be possible, but very unlikely.
If comparing to USD, I would think that the only way for it to be worth $1M would be if the US Dollar experiences hyperinflation.
On top of that, it would need to be adopted worldwide as a legitimate currency for payments.
um the US will experience Venezuela style hyperinflation for printing trillions in $$$ out of thin air. its just a matter of time. and watch bitcoin explode!
This, and/or just think about how Bitcoin is the new type of comodity, never seen in history.. Not backed by physical goods, neighter by political means,.. backed by mathematics..
And it's really scarce in fact.. What is the ratio of BTC/human ?
What could happen to the value if only 1% of every human want to buy 20$ of bitcoin this week ?
This is entering History, like reading a book : we just finished the intro and are at the begining of chapter one !
