I don't disagree that the dollar is a safe haven. I agree. It still has a lot of trust among nations, but what is happening now is that people are looking for alternatives, just in case. So if people are preparing for an "in case", it means that thing is not as trusted as it used to be. People didn't really care about alternatives before; it was gold and the US dollars, but now, people are looking for more because what they're used to may not be enough.
I'm one of those who believe that the US dollar will be a strong and an international trade currency for a long time, ll the talks of de-dollarisation won't change much because what they offer is not better than the dollar, but the point is, now, people want other things, people want alternatives, just in case.
The push for dedollarization is increasing among top BRICS member states but the US dominance over trade transactions is an impediment. Many countries still trade with the US on a large scale and you would need the dollars to make or receive payments.
The loss of confidence the dollar is going through due to Trump's tarriff is forcing people to seek other safe haven assets. Bitcoin is gaining popularity as a safe asset and it's good that people have more investment options.
