On a morning in 2035, I walked into the interstellar immigration service center, preparing to sign a Mars immigration application contract. The hall was spacious and bright, with a flow of people, everything seemed orderly. However, when I sat at the counter and heard a staff member's words, I was instantly stunned.

'Mars immigration application successful, please scan the QR code on the screen to pay the 30 milliBitcoin entry tax.'

'30 milliBitcoin?' I was taken aback and blurted out, 'You no longer accept US dollars?'

The staff smiled slightly, with a hint of sympathy: 'I'm sorry, Mars hasn't accepted any legal tender for a long time. In fact, Bitcoin has become the only legal currency on Mars.'

This was the first time I intuitively felt that Bitcoin is not just an asset but has truly become the foundational order of human society.

Let's turn back the clock ten years, when human society was on the brink of drastic change. The monetary systems of countries around the world were bogged down by high debt, geopolitical conflicts, and excessive money printing. A major economic transformation driven by grassroots technology quietly emerged, with Bitcoin at its center.

At that time, Bitcoin was just a 'star of hope' for some early investors, but over time, it transformed from an investment into the universal language of the global village. This transformation did not happen overnight but was the result of a series of historic events.

For example, the global banking system paralysis incident in 2030. At that time, banks in various countries were paralyzed due to a super virus attack, with core data being widely encrypted, and the entire financial system was on the verge of collapse. People found that whether it was US dollars, euros, or renminbi, none could be used normally. Yet, the Bitcoin network continued to operate as usual, uncontrollable and unalterable. After that incident, Bitcoin was officially established as the standard for global asset preservation and payment tools, and major enterprises and governments began to hoard Bitcoin as part of their foreign exchange reserves.

But the evolution of Bitcoin has not stopped. It is not just an asset store but has slowly permeated everyone's life. The small convenience store at your doorstep only accepts Bitcoin; when you travel abroad, you don't need to exchange currency; just bring your private key. From research stations in Antarctica to remote villages in Africa, as long as you have a smartphone, everyone can trade happily. This 'decentralized' characteristic has completely changed the rules of the world.

On this day in 2035, Bitcoin has transcended the category of currency and has become everyone's social label. In this new world based on digital identity, Bitcoin wallets are not just places to store money; they are also authoritative certification tools.

If you want to enter a top business circle, people won't ask you what degrees you have or how much money you have in your bank. They will only ask you to publicly disclose your wallet address. They will check how much Bitcoin you hold and even your transaction history over the past decade. A wallet with many years of good transaction records can even be directly recognized by private lending institutions outside of banks as the most reliable collateral proof.

Anyone involved in public affairs, whether running for local mayor or applying to the world's top schools, has long made submitting proof of Bitcoin assets a basic requirement. And this 'digital identity' system in a globalized context has completely changed the traditional social credit system.

When I first heard about this system, I couldn't help but complain: 'In the future, will even wedding betrothal gifts have to look at Bitcoin wallets?' My old classmate gave me a hilarious example—he said his cousin is preparing to get married, but the girl's family directly asked, 'Aren't you afraid of running away if you don't hand over the private key?'

I didn't expect that what was once just a joke would become a social norm.

However, the rapid rise of Bitcoin did not come without a cost. The rearrangement of the economic structure benefited a large number of 'holders,' while 'non-holders' were left on the margins in the social elimination race.

A few days ago, I met a college classmate who was once a very talented programmer, but for various reasons, he never got to invest in Bitcoin. When we met, he was holding a beer bottle, cursing.

'What have my former brothers become? One started a private rocket club, calling me every day to party in the Maldives; another keeps sending me crypto art pieces in my friend circle, saying they appreciate tenfold in a year.'

I asked him: 'So why didn't you buy some earlier?'

He snapped at me: 'Why didn't you say it earlier! If I had known it was like this, I would have borrowed money to buy it back then!'

This scene reminds me of the history when Bitcoin surged a hundredfold in 2030. At that time, there were people everywhere mocking Bitcoin as a bubble. Finally, when the bubble theory was thoroughly punctured by reality, this group of people found that they were powerless to reclaim the lost opportunity for wealth.

Bitcoin has not only changed finance; it has profoundly impacted every aspect of the Earth and society. Just last year, a group of environmental scientists proposed a bold idea: using the Bitcoin mechanism to limit carbon emissions!

It turned out that because the Bitcoin network requires a large amount of energy to mine, this demand triggered a surge in renewable energy technology, and technology manufacturers in various countries even launched a 'zero-carbon mining machine competition.' Some scholars proposed that in the future, a carbon credit system could be designed using Bitcoin's smart contracts, linking energy consumption and carbon emissions, directly mapping reduction behaviors as part of the Bitcoin reward mechanism.

This plan has sparked global controversy in a short time. Some say it is a pipe dream, but others believe it will become the starting point for Bitcoin to promote sustainable development. After all, it is a decentralized model without state intervention and complex approvals.

On this day in 2035, looking back at the development trajectory of Bitcoin, I finally understood a principle: Bitcoin has never been a bubble in the financial circle, nor is it just an asset; it is a revolution in economic thought.

It redistributes wealth, makes rules more transparent, and tightens the connection between the economy and technology.

Someone asked me, what exactly is Bitcoin for?

My answer is simple: it is the key to the future. Master it, and you can master choice.

Creating is not easy, please treat me to a hamburger, thank you.
