The united states live from their good reputation.
Although they have already been nearly insolvent a few times during the last years, the USA get negative real interest rates on government debt.
That means the market believes that there are no alternatives with sufficiently low risk.
Hopefully the market is not wrong.
The US credability will be lost soon and the US dollar will crash.
Will bitcoin also crash if dollar crash? most of bitcoin buying through fiat is done with dollar,if it crashes,there will be less buying
