If you mean Tether holders redeeming them for US dollars, that would involve selling treasuries but I doubt it would drive the price down that much. That's a very liquid market.
Selling massive amounts of debt with no additional demand means the required return must be higher.
This is something I’ve needed myself over the last few years as jobs become shorter and shorter lived. Keep on improving it as some kind of compulsion.
My dad flew 32 missions over Germany. He watched men die. 80% of his cohort did not return. He expected to die and made his peace with it. He told me once that when he returned home, he was struck by the trivial problems people had and obsessed over. After all, they weren't flying a mission tomorrow with near certain death.
He said whenever he felt down, he'd recall the men that never had a chance to grow old, and his problems would melt away.
