Can not be denied again that currently bitcoin is the world's strongest currency, the price of 1 bitcoin equal to $ 2500 and marketcap has reached more than 45 billion dollars.
The price of the currency is not talking about her power. It seems to me that the strongest currency at the moment is the us dollar. You can disagree with me, but that's my opinion. The dollar is the currency of the country with the strongest economy in the world. If the Federal Bank will withdraw from circulation all the dollars that the price will be higher than bitcoin.
