Virtual currency linked to RMB
before the advent of bitcoin, all payment systems were based on central authorities (such as banks, payment services, etc.), and customers opened accounts and operated. Therefore, with the permission of the bank, the transaction can be completed through "confirmation", "guarantee" and "execution". At the same time, users need to be completely dependent on banks and other top institutions. Money in the banking system can be monitored, frozen, seized, and cut by inflation
bitcoin system is different. Bitcoin technology enables users not to rely on the guarantee of a third party - all transactions are checked and authenticated by the bitcoin decentralized network, and its functions are also distributed, just like torrent network. Bitcoin system does not belong to anyone, its users are equal, the program source code is open and anyone can view, so as to ensure independence, fairness and security. To create an account and start using bitcoin, users don't have to show their identity or get approval - just connect to the network and install the program wallet. At the same time, all transactions can be carried out directly without freezing. Bitcoin can not only be converted into national currency, but also be used directly in some stores
the independence of bitcoin eliminates the external influence on the network, which is the key advantage compared with the banking system. The timetable of the new bitcoin derived from the algorithm has planned the issuance of the next few decades, directly excluding the uncontrollable inflation in fiat money. No intermediary means no transaction fees or very little. The continuous operation of the network can ensure that users can automatically remit any amount of money in 10 minutes anywhere - without intermediary, restriction and risk. Not long ago, it was hard for people to imagine, but now as long as they can access the network, all this can become a reality.
In the era of gold standard, countries determine their exchange rate by the gold content of their currencies, which is called pegging to gold. The link between the currency and gold is based on the free circulation of gold. During the first World War, the Warring States terminated gold exports one after another, and their currencies devalued sharply. They could no longer exchange gold at a fixed rate. At this time, the currency was actually decoupled from gold< According to the Bretton Woods Agreement of 1944, the currencies of member countries of the International Monetary Fund should be exchanged with gold or US dollar at a fixed exchange rate, that is, linked to gold or US dollar. This agreement established the international monetary status of the US dollar, and the monetary system of various countries established by this agreement is called the Bretton Woods system. In August 1971, the US dollar stopped its free exchange with gold, and the Bretton Woods system collapsed. Then the currencies of various countries no longer exchanged for us dollar at a fixed exchange rate, that is, they were decoupled from the US dollar
exchange rate linkage means that when the main foreign exchange rates rise or fall, the exchange rate of the domestic currency rises or falls together
therefore, at present, the currencies of the world will not and cannot be decoupled from the US dollar.
