Is this a troll question? Ofcourse btc is not bigger than usd that would be crazyness and btc would be way higher in price right now than it is.
Bitcoin is bit but not that big yet by far. We need more advertisement around the whole digital currency idea for it to get more big.
bitcoin have higher price does not mean bitcoin has greater power than the dollar? yeah until whenever the dollar will be more superior than the bitcoin. yeah it's like a very funny question, surely everyone would prefer dollar than bitcoin
If they know the importance of bitcoin im sure that they will try to collect bitcoin.. we are here in forum because we want bitcoin and we are just using bitcoin as alternative and source of income or business.. usd is our real money we can convert our bitcoin in to usd..
If we compare usd and bitcoin only the difference is the price of bitcoin and we are using bitcoin because of anonymity and price of bitcoin is not stable the price can be high or low. .
