The US Dollar may be on the decline, but nobody can say whether it has a few months, years, or decades before it collapses. Right now, the increase in interest rates is making it attractive for global investors who are buying US bonds. The USD has appreciated in value against most global currencies over the past few months.
Until world power under the control on US dollars you cannot get the world countries treated well mate. Please invest you fund on bitcoin and alts with in 5 years you will be find the usage of dollars in some months. Russia and Japan really fighting with US to get rid of from the US dollar usage.
I have heard few months back, after Russia election Vladimir Putin said that Russian government gonna start accept the bitcoin and alts in June month. May be next month we may find the btc rate will be spike up.
