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.
If eur and gbp will be out of the pictuere then imagine dollar purache power..... it's like 1000000% value.
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.
