i have a really hard time with this question.
The answer is, "of course, but..."
The dollar may collapse before we see 1 mil bitcoin.
The dollar may collapse BECAUSE of 1 mil bitcoin.
i believe we will see 1 satoshi = $1.
i believe we will see sending a few satoshi costing $1,000.
But, bitcoin will be relegated to govern-cements settling debts and corporations paying each other.
It will be the currency of buy yachts and mansions.
Which will be great because all us little people will move into Bcash, litecoin and even Digibyte (trading at $1s a piece). All the big money moved into bitcoin, and stabilizing the price.
