This Coinone review examines South Korea’s third-largest cryptocurrency exchange — its fee structure, Kakao Bank integration, regulatory standing, and practical suitability for domestic Korean traders in 2026. Coinone was founded in 2014 and has operated as a consistent mid-tier participant in the Korean domestic exchange market, offering FSC-licensed trading access alongside its two larger domestic competitors, Upbit and Bithumb.
Coinone’s primary differentiators are its Kakao Bank partnership for real-name banking — shared with Upbit’s ecosystem — and a maker-taker fee model that offers lower maker fees (from 0.02%) for traders who provide liquidity. For Korean traders who prioritise limit order trading and want a smaller-platform alternative to Upbit, Coinone presents a regulated, functional option.
Key Takeaways
- Main market fees: 0.20% flat for standard spot trades.
- Maker-taker structure available: maker fees from 0.02%, taker from 0.02% to 0.10% depending on volume tier.
- FSC-licensed and VASP-registered under South Korea’s Special Financial Transactions Act.
- Real-name banking partner: Kakao Bank — shared with the Kakao ecosystem.
- Coinone is one of the few domestic Korean exchanges to offer a formal maker-taker fee schedule, rewarding liquidity providers.
- Spot-only platform; no derivatives or futures trading available.
What Is Coinone?
Coinone was founded in 2014 and has operated continuously as a Korean domestic exchange focused on retail spot trading. The platform obtained FSC VASP registration under the regulations introduced by the Special Financial Transactions Act and maintains a compliance infrastructure aligned with Korean AML and customer protection requirements. Coinone operates under a simpler product model than Upbit or Bithumb, with a focused spot trading interface and no derivatives offering.
Coinone’s Kakao Bank integration for real-name verification aligns it with the broader Kakao financial ecosystem, providing a familiar onboarding path for Korean users who already hold Kakao Bank accounts. For users comparing Korean domestic exchange options, see the exchange directory.
Coinone Trading Fees
| Fee Type | Rate | Notes |
|---|---|---|
| Main market (standard) | 0.20% | Flat rate, both sides |
| Maker (volume-tiered) | 0.02%–0.10% | Lower at higher volume |
| Taker (volume-tiered) | 0.02%–0.10% | Lower at higher volume |
Coinone’s standard 0.20% rate applies to basic account holders, placing it above Bithumb (0.04%) and Upbit (0.05% KRW) at standard access. The tiered maker-taker model, which starts at 0.02% for makers at qualifying volume, provides a mechanism for active traders to reduce costs meaningfully — a structure Upbit does not publicly offer at equivalent simplicity. For traders who place limit orders consistently and can meet the volume thresholds, Coinone’s tiered model can produce lower effective fees than its published standard rate suggests.
Regulatory Standing
Coinone holds FSC VASP registration and operates under the same regulatory framework as Upbit and Bithumb. The exchange is subject to the same AML, real-name verification, and user protection requirements mandated by Korean law for domestic crypto trading platforms. This regulatory parity across the three major domestic exchanges means the compliance standard is consistent; differences between platforms are primarily fee structure, liquidity, banking partnerships, and product range.
Coinone Pros and Cons
Advantages
- FSC-licensed — same regulatory standing as Upbit and Bithumb.

- Clean security record with no confirmed major hack since its 2014 founding.
Limitations
- Standard rate of 0.20% is above both Upbit (0.05%) and Bithumb (0.04%) — fee advantage only materialises for volume-tiered participants.
- Lower liquidity than Upbit and Bithumb means wider spreads on less actively traded KRW pairs.
- Spot-only: no futures, derivatives, or leveraged products.
- Korean residency and Kakao Bank account effectively required for KRW access.
