Why Asia Buys Bitcoin

Blocked paths, tax arbitrage, and the companies they built.

Disclosure, up front: UTXO Management holds positions in companies named in this report, including Metaplanet (TSE: 3350), Moon Inc. (HKEX: 1723), where a UTXO founding partner is chief executive, and Astra (SET: ASTR). Those companies are described structurally, not recommended. Nothing here is investment advice.

The number nobody in the West is looking at

In the twelve months through June 2025, Asia recorded a 69 percent year-over-year increase in on-chain crypto transactions. That is the highest growth rate of any region in the world. Five of the ten most active adopting countries are Asian. In Vietnam, crypto inflows have run near half of GDP.¹

That last figure is the one that matters. Half of GDP does not move through an asset class on a speculative whim. That is not a bull market. That is people solving a problem.

So the question is not whether Asia is adopting Bitcoin. The data settles that. The question is why, and the answer explains something the rest of the world has been getting backwards.

Capital goes around

In much of Asia, the ordinary financial system is the problem rather than the solution. Capital controls. Currency debasement. Remittance corridors that skim eight percent off a construction worker’s wages. Investment channels that are closed by default and opened only by permission. When the legitimate system takes that much off the top, people look for a vehicle that takes less.

The data deserves an honest reading. A great deal of that volume is dollar-seeking, not Bitcoin-seeking. Stablecoins are dollar expansion. They extend the reach of the US Treasury, not the Bitcoin network. China sees this plainly, which is why it bans open crypto while building its own state digital currency, the e-CNY, alongside a domestic blockchain stack. The point is not that China rejects digital finance. It rejects digital finance it does not control.

But the behavior underneath is identical in every one of these cases. Capital is escaping the local system. Whether it escapes into dollars, into Bitcoin, or into an offshore listing depends only on which exit the state left open.

Economists have a name for what happens next: the balloon effect. Squeeze demand in one place and it bulges out in another. Prohibition does not eliminate what it targets; it relocates the activity and frequently concentrates it.² The same dynamic governs capital. Block the direct route and demand does not thin out. It changes shape.

When a state blocks the direct path to Bitcoin, demand does not disappear. It routes around the obstacle and builds a structure. Asia has spent a decade running that experiment across four jurisdictions at four intensities of blockage. The West never ran it at all.

China: the hardest test, and it failed

China is the extreme case.

To understand why China matters, understand that Beijing is not simply the capital. It is the single point from which all Chinese crypto policy radiates, and every province, every exchange, and every bank falls in line behind it. When Beijing moves, the entire country moves at once. That is what makes China the cleanest test of the thesis: there is no internal jurisdiction to route around, only the exit.

China did not become the center of Bitcoin by accident. For most of the last decade it was the network’s beating heart, for two concrete reasons. Sichuan and Yunnan produce enormous hydropower surpluses, and in the wet season miners bought electricity for one or two cents per kilowatt-hour, among the cheapest industrial power on earth. The hardware sat next door, with Bitmain and its peers building the world’s mining machines in Shenzhen. Cheap power and the hardware supply chain together made China, at its peak, roughly three-quarters of global mining capacity.

Then Beijing tried to close the door, in escalating steps. The People’s Bank of China banned Bitcoin as a payment instrument in 2013. Alibaba and Baidu banned Bitcoin transactions and mining-equipment sales in 2014. In 2017 Beijing prohibited fiat-to-crypto exchange, banned ICOs, and shut the domestic exchanges. The stated motive throughout was capital flight, which is to say the state understood exactly what its citizens were doing with this.

The decisive blow came in May 2021, when China banned mining outright. Global hashrate collapsed from roughly 180 exahash to 90 within weeks, a fifty percent drop and the largest forced reduction in Bitcoin’s history. China had been sixty to sixty-five percent of the network. By August its share read as effectively zero.³

That September the PBOC and every regulator that mattered declared all crypto transactions illegal, crypto-to-fiat and crypto-to-crypto alike, still the most severe prohibition any major state has attempted. Beijing reaffirmed it in February 2026.

That decade of prohibition produced something its architects never intended.

Chinese miners are back. Reuters reported in late 2025 that China had returned as the third-largest mining hub at roughly 14 percent of global hashrate, with some trackers putting the figure higher, as capacity quietly rebuilt in Xinjiang and Sichuan where the stranded hydropower always was.⁴The hardware never left at all: Bitmain, MicroBT, and Canaan still manufacture well over 99 percent of the world’s Bitcoin mining machines, Bitmain alone around 82 percent.⁵ The country that outlawed Bitcoin mining builds nearly every machine on earth that does it. And in 2020 Chinese authorities seized 194,775 BTC from the PlusToken fraud, a stash that would rank China among the largest state holders of Bitcoin in the world, though whether Beijing still holds it is genuinely disputed.⁶

The most determined state effort in history to block Bitcoin did not extinguish demand. It displaced it, into quiet mining, into hardware exports, into offshore venues, and into structures the state had not yet thought to name.

That displacement is the whole story of Hong Kong.

Hong Kong: the room the blockage built

Hong Kong’s digital-asset ambitions make sense only in China’s shadow. It is the room where the exposure mainland capital cannot legally hold is nonetheless constructed, licensed, and listed: spot Bitcoin ETFs since 2024, licensed custody, and a stablecoin regime live since August 2025 with real teeth, including full reserve backing, segregated assets, and redemption at par within one business day.⁷

Is it a back door for mainland money? Today, no. Mainland investors cannot buy Hong Kong’s crypto ETFs. Not through Stock Connect, and not through the QDII program, the quota system that lets a limited amount of mainland money invest offshore through licensed institutions. Beijing polices capital-controls bypass attempts aggressively, treating these products as exactly that, which is what they would be. The “Hong Kong back door” line gets repeated constantly by people who have not checked. It is not currently true.

What is true is more interesting, because Hong Kong’s rules dictate what kind of company can exist there. The exchange has pressed firms pivoting into digital-asset treasuries on the listing rules governing excessive liquid-asset holdings, insisting that crypto be integrated into a viable operating business and that holdings cannot be the primary source of a company’s value.⁸ Stated plainly: Hong Kong will not let you list a box of Bitcoin. You need a business.

Good policy or bad, it is the terrain, and it produces a distinct species of company. Boyaa Interactive (0434) holds roughly 4,000 BTC, the only Asian name among the world’s fifteen largest corporate holders, sitting alongside real businesses in online games, Web3, and property. Moon Inc. (1723) is earlier in the same journey, building Bitcoin-linked consumer products on top of an operating prepaid-telecom business, and, as disclosed above, a company UTXO is invested in. It is named here to illustrate the structure, not as a view on its value.

Japan: the arbitrage nobody talks about

Metaplanet’s story has been told many times over. The part that actually matters is usually the part left out, and it is not a treasury story. It is a tax story.

Japan taxes crypto gains as miscellaneous income at rates reaching 55 percent. It taxes listed securities at 20.315 percent. And through NISA, its tax-advantaged retail account, it taxes qualifying equities at zero.⁹

So a Japanese saver who wants Bitcoin faces a direct path taxed at up to fifty-five percent, and an indirect path, a listed equity held inside a NISA account, taxed at nothing. Metaplanet climbed to the top of SBI’s and Rakuten’s weekly NISA purchase rankings, above blue-chip industrials, because Japanese retail was routing around a thirty-five point tax wedge.

That is the whole engine, and it is closing. Japan’s 2026 reform moves crypto under the Financial Instruments and Exchange Act with a flat 20 percent separate tax, effective around January 2028.¹⁰ The gap that built the wrapper very nearly disappears. A sliver survives, since NISA still shelters equities at zero, but the chasm becomes a crack.

Korea: proven demand, walled in

Korea requires precision, because the easy version of this story is wrong.

Koreans have always been able to buy and sell Bitcoin. Domestic won exchanges are enormous: Upbit alone runs around 70 percent of the market, and Upbit and Bithumb together roughly 98 percent.¹¹ So the demand was never in question. What proves it is the kimchi premium, the persistent gap between the won price of Bitcoin and the global dollar price, which at times has run above ten percent. A premium like that exists for one reason: capital controls trap domestic demand onshore, where it cannot arbitrage against the rest of the world. The appetite is real, and it is provably walled in.

What Korea blocked was not ownership. It was structure. Spot crypto ETFs have been prohibited since 2017 under the Capital Markets Act, which did not recognize digital assets as eligible ETF underlyings, and Korea went further and banned ETFs that tracked crypto-related companies.¹² Institutions and corporations were locked out of holding crypto entirely. So the country had furious retail demand, no regulated wrapper, and no institutional access. That is the gap a listed vehicle fills.

And the walls are coming down. The Financial Services Commission is fast-tracking amendments and has greenlit spot Bitcoin ETFs for 2026, and the nine-year ban on corporate crypto holdings lifted in January 2026, capped at 5 percent of shareholder equity.¹³ Proven, trapped demand is about to be handed regulated vehicles for the first time.

Thailand: the control group

Here the argument stops being a story and becomes something you can test.

Thailand did the opposite of Japan and Korea. Rather than blocking the direct path, it cleared it. Under Ministerial Regulation No. 399, gazetted in September 2025, capital gains on crypto sold through Thai-licensed venues are entirely exempt from personal income tax from January 2025 through December 2029.¹⁴ Peer-to-peer and OTC trades do not qualify, which is deliberate: the exemption is designed to pull activity onshore, into the licensed perimeter.

The politics are unusually explicit. Thaksin Shinawatra, prime minister from 2001 to 2006 and the dominant force in Thai politics for the two decades since, has become one of the most prominent political advocates for Bitcoin anywhere in the world, proposing a Bitcoin-payment sandbox for Phuket’s tourism sector, floating government-bond-backed stablecoins, and campaigning for Thailand to become ASEAN’s digital-asset hub.¹⁵ A former head of government arguing publicly that his country should adopt Bitcoin is not a posture you find elsewhere in the region.

In Thailand the direct path is open and untaxed, and notice what did not emerge: no tax-wrapper treasury equity. There was nothing to arbitrage. The opportunity moved instead to infrastructure, to custody and exchanges and payment rails, the plumbing a legal onshore market actually needs. It shows up in the deals. Astra (SET: ASTR), a UTXO holding as disclosed above, acquired Rakkar Digital, one of only two SEC-licensed digital-asset custodians in Thailand, originally built as a joint venture between Siam Commercial Bank’s SCBX and Fireblocks, with more than 700 million dollars under custody.¹⁶ When the state opens the path, the money to be made is in the rails, not in a wrapper around the toll booth.

That is exactly what the thesis predicts. Japan blocked the path with tax and got a wrapper. Korea blocked it with access rules and got trapped demand waiting for one. China closed it entirely and got underground mining and an offshore venue. Thailand opened it and got infrastructure. Four jurisdictions, four intensities of blockage, four structures, each the precise shape of the obstacle it grew around. The variance is the evidence.

What survives when the arbitrage closes

If the wrappers exist because of distortions, and the distortions are being dismantled, what is left?

The ordinary answer in equities: a business. A company whose only advantage was the tax or access wrapper loses that advantage when the tax code changes or the ETF arrives. A company with a real operating business underneath does not. That is not a value judgment about any company. It is a structural observation about what happens to a vehicle when the specific reason it existed expires.

The environment is pushing the same way from two directions at once. Hong Kong requires an operating business as a condition of listing. And MSCI, in late 2025, proposed excluding companies with more than half of their assets in digital assets from its global indices, which would have forced an estimated ten to fifteen billion dollars of passive selling. MSCI deferred the decision in January 2026 but flagged a broader review of non-operating companies.¹⁷ Exchanges and index providers are independently converging on the same distinction.

The best operators are not waiting. Metaplanet is pushing into fee-generating financial businesses precisely because management can see the wrapper edge expiring. And the market is already ahead of the commentary. Both Metaplanet and Boyaa have traded below the value of their Bitcoin at points in 2026. The caricature of the Asian Bitcoin equity as a leveraged proxy that only goes up is out of date in both directions.

What would prove the thesis wrong

The diagnosis holds with more conviction than the timing, and the distinction is worth stating plainly.

The reforms could slip. Japan’s tax change is not fully effective until 2028, and Korea’s approvals could be delayed. If so, the arbitrage persists longer than expected, and the thesis is early, which in practice is indistinguishable from being wrong. The operating businesses could fail to deliver, and most of them are small, some lossmaking today. Discounts to net asset value can persist for years, as holding-company discounts do in every market on earth, with no catalyst obliged to arrive. And Bitcoin itself remains capable of humbling everyone. The total crypto market fell from 4.4 trillion dollars in October 2025 to 2.6 trillion by April 2026.¹⁸

The thesis does not need every jurisdiction to work. It needs a few of the region’s major markets to convert this adoption into durable participation. If fewer do, then Asia was early to something that arrived slowly, or did not arrive at all.

Why it matters

The reason to watch Asia is not that Asia is bullish. Everyone in this industry is bullish. It is the least informative thing a person can be.

The reason to watch Asia is that Asia ran the experiment first. Picture the obstacle in the middle, the state saying no. China said it loudest, and the demand did not stop. It piled up on either side of the wall and built structures that grew taller and stronger the harder the wall pushed back: mining that came back from zero, an offshore market in Hong Kong, tax-advantaged equities in Tokyo, trapped billions in Seoul waiting for a door. When a state makes the direct path to Bitcoin expensive, illegal, or impossible, capital does not stop. It builds around the obstacle, and it builds high.

Those experiments are ending, one by one. What they leave behind, operating companies with Bitcoin on the balance sheet, is the durable form, and it is the form the rest of the world will arrive at eventually, from a different direction and several years late.

The laboratory has been running in plain sight. Very few people were watching it.
