The Line That Matters: Whose Assets Are You Trading?
Automated crypto trading — running bots that execute strategies algorithmically across virtual asset exchanges — is not inherently illegal in Korea. Korean law does not prohibit algorithmic trading as such. What it does regulate, sharply, is who you are trading for. Operating a bot on your own account is categorically different, in Korean law, from operating a bot that manages someone else’s assets. That distinction determines whether you need regulatory authorization, and whether you are exposed to criminal liability.
At Cha & Kwon Law Offices, we advise clients across the spectrum of automated trading — from individual quant traders to teams offering bot-as-a-service products targeting the Korean market. The legal risks are real and frequently underestimated.
Risk One: VASP Registration When You Trade for Others
Korea’s Act on Reporting and Using Specified Financial Transaction Information (“SFTIA”) defines a Virtual Asset Service Provider (VASP) as any entity that, as a business, engages in — among other things — the transfer of virtual assets. “Transfer” in the SFTIA context means moving virtual assets from one person’s account or wallet to another’s, including on behalf of users.
This creates a direct legal problem for certain bot business models. If your trading bot moves virtual assets between wallets or accounts on behalf of users — as part of a managed trading service, a bot rental arrangement with profit sharing, or a copy-trading platform — you are operating as a VASP without authorization. KoFIU (Korea Financial Intelligence Unit) registration becomes mandatory. Operating as an unregistered VASP carries criminal penalties of up to five years imprisonment or KRW 50 million in fines under the SFTIA.
The safe structure is straightforward: bots operating exclusively on the operator’s own account, with the operator’s own capital, do not trigger the VASP transfer analysis. Problems arise when the business model involves touching other people’s assets — whether through custody, delegation, or transfer.
Risk Two: Investment Discretion Rules Under the Capital Markets Act
A second layer of regulation applies when a bot operator exercises investment discretion over other people’s assets. Korea’s Capital Markets Act requires a license for “investment advisory” and “discretionary investment” businesses. Discretionary investment — where a manager has authority to make investment decisions on behalf of a client — requires Financial Services Commission (FSC) authorization regardless of whether the underlying assets are securities or virtual assets.
Virtual assets are not currently classified as securities under the Capital Markets Act in most cases. However, the FSC’s position has been that where the economic substance of an arrangement involves managing client funds with investment discretion, regulatory obligations may apply even if the assets sit outside the traditional securities perimeter. Bot operators offering managed strategies — particularly where clients deposit funds and the operator controls trading decisions — are exposed to serious compliance risk and demand immediate legal counsel review before launch.
Risk Three: Market Manipulation Under the Virtual Asset User Protection Act
The Virtual Asset User Protection Act (“VAUPA”), effective July 2024, introduced explicit prohibitions on market manipulation in virtual asset markets. These provisions mirror the market abuse framework in the Capital Markets Act and apply to conduct on Korean virtual asset exchanges.
Prohibited conduct under VAUPA includes wash trading, layering, spoofing, and other strategies designed to create a false impression of market activity or artificially move prices. These are precisely the strategies that certain high-frequency and arbitrage bots execute — and the fact that the conduct is automated does not provide a legal defense. Korean regulators and prosecutors look at the effect of the trading pattern, not the intent of the individual keystroke.
Bot operators whose strategies produce patterns that resemble wash trading or layering face exposure under VAUPA even if the underlying intent was market-neutral. Liability under VAUPA market manipulation provisions carries criminal penalties, and the FSC and Financial Supervisory Service (FSS) have signaled active enforcement attention on virtual asset markets following the law’s enactment.
What Compliant Bot Operation Looks Like
Own-account trading: A bot trading exclusively with the operator’s own capital, on the operator’s own exchange accounts, does not trigger the VASP transfer analysis and avoids the investment discretion issues entirely. This is the lowest-risk structure.
Subscription or licensing models: Providing bot software for users to run on their own accounts — where the user controls their own credentials and capital — generally avoids VASP and discretionary investment characterization. The operator is providing software, not managing assets. Legal review of the service agreement and technical architecture is still advisable.
Revenue sharing and managed accounts: Any structure where the operator has access to user funds, moves assets on behalf of users, or receives performance fees tied to trading outcomes requires careful legal structuring. These arrangements are the highest-risk category and should be reviewed before launch.
What Cha & Kwon Advises in Practice
We work with automated trading operators to assess whether their business model crosses the VASP and investment discretion thresholds under Korean law, and to structure arrangements that minimize regulatory exposure. Three variables consistently determine your legal standing: who holds the assets, who controls the trading decisions, and how you structure your fee model. Determining these factors before product launch is materially less costly than navigating regulatory enforcement afterward.
