Dude,stop preaching about things that might not happen.
The US dollar will remain a global reserve currency with or without the corona pandemic and the corona recession.The US economy is still the strongest economy in the world and the majority of the people around the world trust the US dollar,because it is a well known and stable currency.
I'm not advocating and I'm not the biggest US dollar fan,but this is the reality.The euro and the yen aren't even close to the US dollar,in terms of global usage.
It is quite sad, but you are mainly right.
Except one moment - now USA made the decision to print a lot of money in order to give out to their citizens.
What does it mean for usd holders out there - they've lost some value of their assets on hands which really sucks.
This made a lot of investors will to exchange their usd to prevent further losses (which is absolutely adequate).
So by that I mean - crypto could really become one of the main hodl instruments in nearest time
