Since 1944 the USD has become a global reserve currency, so the weakening and strengthening of the USD will affect the fiscal policies of other countries and the price of financial instruments, one of which is Bitcoin. To measure the average level of weakening and strengthening of the USD against a particular country's currency (busket currency), DXY or DXY Dollar Index is needed. Meanwhile, the currency used as the benchmark (busket currency) consists of EUR, Yen, GBP, CAD, SEK and CHF.
