It doesn't make sense. But it is a fact. The value of dollars raised by foreign corporations via bonds that have to repaid in dollars is $10 trillion since 2008.
The Hong Kong dollar is pegged to the US dollar. The Chinese Yuan has been more or less pegged the US dollar. This policy enabled China to force all savings in China into 0 profit manufacturing. Read Michael Pettis to understand the macro economics.
What you think is irrelevant. These are the facts.
I mean, it's obvious why, just military dominance. They have no need to challenge the dollar in a way that can create conflict until the burden of not doing so is too great. That time will come and everyone on the planet is not going to be willing slaves of the US forever. Even if they were willing to do such a thing, the flight of capital to the US would send Bitcoin to the moon in the process. I think this debunks your idea that gold and Bitcoin can be linked at all completely. Capital flight to US assets or USD will send Bitcoin skyrocketing. Bitcoin is the Rolls Royce of capital flight.
YUAN => BTC (increase of BTC price)
BTC => USD (decrease of BTC price)
isnt the effect neutral at the end? or am i missing something?
No...because the market cap is dramatically inflated in the process, which makes the price of each coin go higher. Not everyone is buying then dumping all at the same time. The float of economic activity is what enables you to use any currency as a store of value. It's a hugely net positive effect.
