Bitcoin was created to provide independence from Government control to the users. But I think it is not so independent. ..............
Kindly correct me if I am wrong.
Exactly. If bitcoins are decentralized and a currency itself then how can it depend on any other type of currency and why should it?
Bitcoin does not explicitly depend on the dollar, but at the moment the dollar is the standardized measure of value in the world as the most popular and well-known currency. Their dependence can be manifested with the general market fluctuations, but usually they affect the entire financial market.
