Your investment in Bitcoin doesn't impact me one way or the other, and I don't have a motive nor a massive ego. I hope people know what they're getting into and don't get ripped off.

If Bitcoin has as much intrinsic value as the USD, why did foreign nations and businesses seek the dollar over Bitcoin during the pandemic, and now?

The USD has a population of 340 million, a government, military, an economy, a reserve bank, and global acceptance. Bitcoin doesn't have a monetary policy, and I think you've confused policy with supply. Bitcoin could be $50 today and $5 tomorrow, and a Tweet, mining, gov regulation, etc impact its value.

How long does it take to pay someone using Bitcoin and does everyone accept it as payment?

How does a decentralized currency make it valuable? What makes Bitcoin valuable?
