Why is the USD losing value?

Could you elaborate on the reasons behind the declining value of the US Dollar? Is it due to the rising popularity of cryptocurrencies, which are often seen as an alternative to traditional fiat currencies? Or perhaps the influx of fiscal stimulus packages, resulting in an increase in government debt, thereby diminishing the USD's perceived value? Are there any geopolitical tensions or economic uncertainties that are contributing to the USD's weakness? I'm interested in understanding the multifaceted factors that are driving this trend and how it might impact global financial markets in the long run.
