If central banks of various countries really treat Bitcoin as a reserve asset, the world might look like this:

1. The position of the US dollar as the dominant currency may become unstable.

Currently, global trade is mainly settled in US dollars, but Bitcoin, which is a 'wild currency' not controlled by any country, could weaken the influence of the dollar. For example, small countries like El Salvador have long used Bitcoin as a talisman to counteract dollar hegemony. However, the US is also calculating its options, possibly wanting to create a 'dollar + Bitcoin' dual insurance to continue being the world bank president.

2. Countries' saving methods will change.

Currently, countries mainly save in gold and US dollars, but in the future, they may also want to save some Bitcoin. Recently, the Czech Republic proposed that the country try saving some Bitcoin to test the waters, but the price of Bitcoin is like a roller coaster—profitable today and losing tomorrow. Small countries might manage it, but large countries may not dare to play too big.

3. Technologically strong countries will compete for new territory.

In the future, whoever can control the Bitcoin network will have a say. The US is currently encouraging Bitcoin innovation while also fearing potential problems, like walking a tightrope. China, although currently strict in control, also has strong digital currency technology, and one day they might surprise everyone.

4. Financial risks may become more stimulating.

The Bitcoin market is now similar to a casino; if countries really hold a lot of Bitcoin, a sudden drop could lead to significant losses in national accounts. Moreover, this thing can also be used to evade international sanctions, making it harder to crack down on economic crimes in the future.

5. Three possible outcomes:

1. Good outcome: Bitcoin becomes 'digital gold,' making countries' finances safer and cross-border transactions instant.

2. Bad outcome: Bitcoin collapses the economies of a few small countries, becoming a new weapon in financial warfare.

3. Middle ground: Bitcoin serves as a backup reserve, used only in specific situations, and does not cause major waves.

In short, whether this can work depends on three key points: whether Bitcoin's price can stabilize, whether countries can reach a consensus on regulation, and whether blockchain technology is secure enough. It's currently like playing a financial version of 'Squid Game,' with countries testing the limits; whoever finds the balance point first will be able to reap the rewards.
