Now we see why the USA moving towards crypto and they created new dollar the USDC and USDT and other stablecoins to make sure people have a lot ways to adobt dollar.
You better stack up the dollars

dollar is now like ico you get in early
The idea of stacking up dollar is something I see as unnecessary or not advisable, during war the economy of a country is being affected and thus leading to the devaluing of the currency which is to say, if definitely there should be war in the European countries or wherever there's much tendency that it'll sure affect the value of USD.
And I don't think the USA are moving towards crypto space because looking at their past political state and history since the rise of Bitcoin it has caused some many chaotics events and yes so many people have so much faith in dollars because it's one of the top exchanges in the world which makes it more volatile and easily accessible but it won't suit in in the situation of war cause of price fluctuations.
EU has been pushed to have a war against Russia by the narrative that EU's security depends on the survival of Ukraine. But obviously, Russia has no reason to obliterate the whole of Ukraine. They have to give Zelensy the right to target inside Russia to make Russia attack them again but every time they do it, they are met with a more powerful counterattack.
EU has more to lose if they don't want to lose more while Turkey is joining BRICS, they have to balance their act since BRICS confirmed their currency is backed by gold.
