In the evolving landscape of digital asset adoption, few companies have quietly amassed a more impressive Bitcoin (BTC) reserve than Dunamu Inc., the operator of South Korea’s largest cryptocurrency exchange, Upbit. By leveraging a systematic, revenue-driven accumulation strategy akin to dollar-cost averaging (DCA), Dunamu has built a Bitcoin treasury worth approximately $1.8 billion—placing it among the top corporate holders globally. This deep dive explores how Upbit’s unique business model fuels its BTC growth, the sustainability of its strategy, and what it means for investors and the broader crypto ecosystem.
The Rise of Bitcoin as a Corporate Asset
Bitcoin’s transformation from speculative digital token to institutional-grade asset has been cemented by milestones such as the approval of U.S. spot Bitcoin ETFs and increasing macroeconomic recognition of its scarcity-driven value proposition. As confidence in Bitcoin as a long-term store of value grows, a new class of “Bitcoin-native” enterprises has emerged—companies that not only facilitate crypto trading but actively accumulate BTC through operational revenue.
While firms like MicroStrategy and Metaplanet are known for aggressive balance sheet strategies using debt or equity financing, Dunamu stands out for a different reason: it acquires Bitcoin organically through everyday exchange activity. This makes its accumulation model both sustainable and reflective of real user demand.

How Upbit Accumulates Bitcoin: A Revenue-to-BTC Engine
As of December 2024, Dunamu held 16,839 BTC, ranking fourth among publicly traded companies and tenth globally when including private firms. This position was achieved not through one-time purchases but via consistent reinvestment of revenue generated from two core services:
- BTC Market Trading Fees
- Bitcoin Withdrawal Fees
These streams function as an automated DCA mechanism—every trade and withdrawal effectively “buys” more Bitcoin for the company.
1. BTC Market Trading Fees: The Primary Fuel
Upbit operates three major trading markets:
- KRW-BTC (Korean won pairs)
- BTC-ALT (Bitcoin-based altcoin pairs)
- USDT-ALT (Tether-based altcoin pairs)
Of these, the BTC-ALT market is the most significant source of Bitcoin inflow. With 222 listed BTC pairs as of May 2025, Upbit charges a 0.25% fee on both sides of each trade—paid in BTC. This means every transaction directly adds Bitcoin to Upbit’s coffers.
Historically, this model proved highly effective:
- In 2023: ~696,201 BTC traded → ~3,481 BTC collected in fees
- In 2024: Volume dropped sharply to ~165,166 BTC → ~826 BTC in fees
Despite the decline, BTC market fees accounted for over 90% of Dunamu’s total Bitcoin acquisitions, making it the dominant engine behind its accumulation strategy.
2. Bitcoin Withdrawal Fees: High Margin, Low Volume
When users withdraw BTC from Upbit, they pay a fixed fee—0.0008 BTC per transaction as of 2025. While seemingly small, these fees contribute meaningfully due to their near-zero marginal cost.
On-chain data reveals that average network fees (paid by exchanges to miners) are around 0.00002–0.00009 BTC. With Upbit charging up to 40x that amount, the gross margin on withdrawal fees exceeds 99%.
However, scalability is limited:
- Estimated annual BTC collected from withdrawals: 91–437 BTC
- Realistic net contribution after internal costs: under 100 BTC/year
Though profitable, withdrawal fees alone cannot sustain large-scale accumulation.
3. International Licensing: A Minor Contributor
Dunamu also partners with regional exchanges like Upbit Thailand and Upbit Indonesia through technology licensing agreements. While some BTC fee revenue may flow back via these contracts, analysis suggests their impact is minimal—likely contributing fewer than 10 BTC annually.
Thus, Dunamu’s Bitcoin growth remains overwhelmingly tied to domestic trading activity on its core platform.
Challenges to Sustained Accumulation
While Upbit’s DCA-like strategy has delivered remarkable results, several structural shifts threaten its continuation at previous rates.
Declining BTC Trading Volume
Since the launch of U.S. spot Bitcoin ETFs in early 2024, investor behavior has shifted dramatically. Bitcoin is increasingly viewed not as a trading medium but as a long-term store of value—leading users to hold rather than trade BTC-denominated pairs.
The result?
- 72% drop in BTC market volume from Q1 2024 onward
- Annualized 2025 volume projected at just 25,441 BTC—a 96% decrease from 2023 levels
Without intervention, this trend could render the BTC market fee stream negligible within two years.
Competitive Pressure on Withdrawal Fees
Global exchanges like Binance (0.00003 BTC), OKX (0.00002 BTC), and MEXC (0.00001 BTC) charge significantly lower withdrawal fees than Upbit (0.0008 BTC). As international competition intensifies, Upbit faces mounting pressure to reduce fees to remain competitive—especially for institutional and high-frequency traders.
Even if fees are gradually lowered, maintaining profitability will require either:
- Cost optimization via cold wallet management
- Adoption of Layer 2 solutions like the Lightning Network
But without such innovations, this revenue stream will shrink further.

Financial Impact and Valuation Implications
Dunamu’s Bitcoin holdings aren’t just operational byproducts—they’re strategic assets with material financial implications.
Hidden Value in Revaluation Gains
Under accounting standards, Bitcoin is classified as an intangible asset. When its market value rises, companies can revalue their holdings, increasing equity without affecting profit-and-loss statements.
In 2024 alone, Dunamu’s equity increased by $1.1 billion due to Bitcoin revaluation—a gain invisible in net income reports but critical for accurate valuation.
Yet, this factor is often overlooked by traditional analysts who focus solely on operating margins and revenue growth.
Market Cap vs. On-Chain Reality
With a market capitalization of $3.9 billion, Dunamu trades at a significant discount compared to peers like Coinbase—especially when adjusting for BTC reserves. While Coinbase offers broader services (e.g., Base chain, Deribit options), Dunamu’s concentrated exposure to Bitcoin presents a purer investment thesis.
However, investors must avoid overestimating future accumulation potential. Assuming continued rapid growth ignores clear headwinds in volume and fee compression.
Frequently Asked Questions (FAQ)
Q: Is Dunamu intentionally buying Bitcoin?
A: There’s no public confirmation of a formal BTC acquisition policy. However, its business model naturally leads to accumulation through fee collection—functioning like an organic DCA strategy.
Q: Can Upbit keep growing its Bitcoin stash at the same pace?
A: Unlikely. With BTC market volume down 72% post-ETF approval and rising competitive pressure on withdrawal fees, sustained high-speed accumulation is no longer feasible without direct cash purchases.
Q: How does Upbit compare to MicroStrategy in Bitcoin strategy?
A: MicroStrategy uses debt and equity financing to buy BTC aggressively. Dunamu accumulates passively via revenue—making it less risky but also slower-growing unless market conditions improve.
Q: Could Dunamu sell its Bitcoin holdings?
A: Regulatory restrictions on corporate crypto dispositions have eased since 2025. While no sales have been reported, increased flexibility means future disposals are now possible—potentially impacting market sentiment.
Q: Why does Upbit charge higher withdrawal fees than global exchanges?
A: Higher fees may reflect legacy infrastructure costs or strategic pricing. However, with growing competition and user demand for lower costs, a downward adjustment seems inevitable.
Q: What could revive Upbit’s BTC accumulation?
A: Reviving interest in BTC-denominated trading would require new incentives—such as staking rewards, yield-bearing products (BTCfi), or derivatives like perpetual swaps on BTC pairs.
Conclusion: A Model at a Crossroads
Dunamu has become one of the world’s most significant corporate Bitcoin holders—not through bold announcements or leveraged bets—but through disciplined execution of a simple idea: turn transactional revenue into strategic reserves.
Its journey reflects a broader shift in how businesses view digital assets—not as liabilities or risks, but as durable stores of value capable of transforming balance sheets.
Yet, the era of rapid accumulation appears to be ending. Structural declines in BTC trading volume and competitive pressures on fees suggest that Dunamu’s organic DCA engine is slowing.
Going forward, its strategy may evolve in one of three directions:
- Double down on Bitcoin: Use cash profits to buy more BTC directly.
- Diversify services: Launch derivatives, lending, or DeFi integrations to boost volume.
- Monetize holdings: Begin selective disposals now that regulations allow greater flexibility.
For investors and observers alike, Dunamu’s next moves will offer valuable insights into how mature crypto-native firms navigate post-adoption realities.
