The world of cryptocurrency is witnessing a quiet revolution—not in decentralized protocols or meme coins, but within the balance sheets of major exchanges. One name stands out in this transformation: Upbit, South Korea’s largest digital asset platform, operated by Dunamu Inc. By the end of 2024, Dunamu had amassed 16,839 BTC, valued at approximately $1.8 billion, positioning itself as the 4th largest publicly traded company holder of Bitcoin globally—and 10th if private firms are included.
This accumulation wasn’t achieved through debt financing or speculative bets. Instead, Dunamu has quietly executed one of the most consistent dollar-cost averaging (DCA) strategies in corporate history—funded almost entirely by Bitcoin-denominated transaction and withdrawal fees from its own users.
But with shifting market dynamics and increasing competitive pressure, can this strategy continue?
The Emergence of Bitcoin as a Corporate Reserve Asset
Bitcoin’s journey from fringe technology to institutional-grade asset class accelerated dramatically with the approval of spot Bitcoin ETFs in the U.S. This regulatory milestone validated Bitcoin not just as a speculative instrument, but as a legitimate store of value—a digital gold alternative.
In response, a new class of corporations has emerged: Bitcoin-centric balance sheet managers. Companies like MicroStrategy and Tether have made headlines for their aggressive BTC acquisition strategies. Tether, for instance, announced in 2023 that it would allocate up to 15% of its net profits toward Bitcoin purchases—a move framed as both financial prudence and ideological alignment with decentralized finance.
Yet, while many firms buy Bitcoin using cash reserves or raise capital specifically for BTC, Dunamu’s model is unique: it uses organic revenue streams denominated in Bitcoin itself to accumulate more Bitcoin—effectively running a self-reinforcing cycle of BTC inflow.

How Dunamu Built Its Bitcoin Fortress
Dunamu’s Bitcoin accumulation stems directly from Upbit’s core business operations. Unlike traditional companies that convert revenue into fiat and later invest in crypto, Upbit collects fees in Bitcoin, which are then recorded on the company’s books as income—and retained as strategic holdings.
Primary Sources of Bitcoin Revenue
- BTC Market Trading Fees
Upbit operates three primary markets: KRW-BTC, BTC-Altcoin, and USDT-Altcoin pairs. For every trade on the BTC market, Upbit charges a 0.25% fee on both sides, paid in Bitcoin. With hundreds of listed assets and deep liquidity, these fees generate substantial BTC inflows annually. - Bitcoin Withdrawal Fees
When users withdraw BTC from Upbit, they pay a fixed fee—historically ranging from 0.0009 to 0.0008 BTC per transaction. While seemingly small, these fees accumulate rapidly across thousands of withdrawals. - Potential Revenue from International Partnerships (Uncertain)
Through its technical alliance with Upbit APAC Pte. Ltd., Dunamu may receive BTC-based fees from international operations such as Upbit Thailand and Indonesia. Although exact figures aren’t disclosed, financial reports suggest some cross-border revenue sharing occurs.
Accounting Treatment: A Silent DCA Machine
From an accounting perspective, each time Upbit receives BTC as income—whether from trading or withdrawals—the following journal entry applies:
Debit: Intangible Assets (BTC) / Credit: Revenue
This means Dunamu doesn’t “buy” Bitcoin with cash—it simply retains what it earns in BTC form, effectively executing a continuous DCA strategy without market timing risk.
In 2023 alone, Dunamu “acquired” 3,918 BTC through this method—representing 13.56% of its $769 million revenue**. In 2024, despite declining volumes, it still added **917 BTC**, or **4.62% of $1.3 billion in revenue.
The Decline of BTC Market Activity: A Structural Shift?
Despite its success, Dunamu’s accumulation engine faces headwinds.
Plummeting BTC Trading Volumes
Since the launch of U.S. spot Bitcoin ETFs in early 2024, trading activity on Upbit’s BTC market has collapsed:
- 2021: ~1.53 million BTC traded
- 2023: 696,201 BTC
- 2024: Just 165,166 BTC — a 76% drop year-over-year
- 2025 (annualized): Projected at only 25,441 BTC
This sharp decline correlates with a broader market shift: users now treat Bitcoin primarily as a store of value, not a medium of exchange for altcoin speculation. As ETFs offer regulated exposure without custody risk, demand for BTC-based trading pairs has weakened.

Withdrawal Fees Under Pressure
While withdrawal fees appear highly profitable—charging 0.0008 BTC versus actual network costs of ~0.0000022 BTC—this margin is unsustainable long-term.
Global competitors like Binance (0.00003 BTC) and OKX (0.00002 BTC) charge significantly less. Even MEXC charges only 0.00001 BTC. Upbit’s current rate is roughly 40 times higher than industry standards.
Though high fees contribute to BTC accumulation now, competitive forces will likely push them downward—especially as users migrate to cheaper platforms.
Moreover, withdrawal activity isn’t scalable. Even under optimistic assumptions, annual BTC gains from withdrawal fees likely won’t exceed 100–150 BTC after operational costs.
Can Upbit Sustain Its Accumulation Pace?
The short answer: no—not without strategic changes.
Without drastic interventions like direct cash-funded Bitcoin purchases or new revenue models, Dunamu cannot maintain its previous accumulation speed due to:
- Shrinking BTC-denominated trading volume
- Regulatory and competitive pressure on withdrawal fees
- Limited scalability of fee-based BTC income
Even if Dunamu retains all BTC earned via fees, future annual additions may fall below 500 BTC, far less than the 3,918 BTC added in 2023.
However, there’s a silver lining: regulatory clarity is improving.
As South Korean authorities ease restrictions on corporate crypto holdings and tax treatment, Dunamu may gain flexibility in managing its $1.8 billion BTC treasury—potentially unlocking new strategies such as:
- Strategic sales during bull markets
- Use of BTC as collateral for yield-generating activities
- Public disclosure of a formal treasury policy
Valuation Implications: Is the Market Underpricing Dunamu’s BTC Holdings?
Despite widespread coverage of Dunamu’s profits, few analyses account for the strategic value of its Bitcoin reserves.
Hidden Balance Sheet Value
At year-end 2024, the revaluation of Dunamu’s BTC holdings increased its equity by $1.1 billion—an amount not reflected in operating or net profit figures. Yet this unrealized gain significantly boosts shareholder value.
With a current market cap of $3.9 billion, investors evaluating Dunamu based solely on P/E ratios may be missing a critical component: its growing digital asset treasury.
For comparison:
- Coinbase operates in futures, staking, and Layer 2 ecosystems (Base), giving it broader revenue diversity.
- But when adjusting for BTC reserves, the relative valuation gap between Coinbase and Dunamu becomes a compelling discussion point.
That said, investors should avoid assuming perpetual accumulation. Future growth must come from innovation—not just passive fee retention.

Q: Why is Upbit’s withdrawal fee higher than other exchanges?
A: While currently at 0.0008 BTC, it remains above global averages due to historical pricing strategy. Competitive pressures suggest it may decrease over time.
Q: Could Dunamu sell its Bitcoin?
A: Yes. Regulatory barriers to corporate crypto disposal have eased since 2025, allowing greater flexibility in treasury management.
Q: How does Upbit compare to MicroStrategy or Tether?
A: Unlike MicroStrategy (which leverages debt) or Tether (which allocates profits), Upbit uniquely grows its stash via native platform revenue—making it a rare example of organic corporate BTC accumulation.
Final Thoughts: A New Era for Crypto-Native Corporations
Dunamu has become an accidental pioneer—a publicly traded company operating like an extreme Bitcoin maximalist, reinvesting platform revenues into the very asset underpinning its ecosystem.
Its story illustrates a powerful trend: crypto-native businesses can build self-sustaining economic models where revenue and reserves align in the same digital asset.
Yet sustainability depends on adaptation. To remain relevant, Upbit may need to expand into derivatives, lending, or global markets—or risk slowing its once-impressive accumulation pace.
As the line between exchange and treasury blurs, Dunamu serves as both case study and cautionary tale: in the age of digital assets, how companies manage their balance sheets may matter more than their trading engines.
