However, I realized that the main goal of BTC marketing aims to grab US dollars over the world, then destroy them using the dynamic changes of the price of BTC. The overall goal is to decrease the amount of the supply of US dollars. BTC let people all over the world pay the bill signed by Trump and Biden.
1. There's no such thing as "Bitcoin marketing"
2. So that non-existing entity will "grab" dollars and destroy them? How? Do you know that the central banks/federal reserves are the only ones entitled to
destroy the money? Or what you mean? I think that you are awfully confuse things here.
3. About "the bill" you are
somewhat right though. But it's not only Trump and Biden. Most leaders have using the money printing machine at full power. That means that the (existing) money's value decreases more and more. Bitcoin is not making others do anything special. But Bitcoin may help those owning some coins not lose money due to all fiat currencies' inflation. So again, Bitcoin, amongst some other investments, can be a hedge against inflation. That's all.
But Bitcoin/bitcoiners don't do anything special. It's the governments that create inflation and it's the others that don't fight against getting poorer.
All in all, you've seen something there, but because of confusions on how the things work, you may be seeing them from the wrong angle.
