Three exchanges — Binance, Bybit, and OKX — control a large share of global crypto trading volume. For most arbitrageurs, these are the core working toolkit. But despite their surface similarities, each has distinct strengths — and knowing those differences directly impacts profitability.
Here's a head-to-head comparison across 10 criteria that matter specifically for arbitrage.
1. Trading Fees
| Tier | Binance | Bybit | OKX |
|---|---|---|---|
| Standard Maker | 0.10% | 0.10% | 0.08% |
| Standard Taker | 0.10% | 0.10% | 0.10% |
| With native token | 0.075% (BNB) | — | — |
| VIP1 Taker | 0.09% | 0.10% | 0.08% |
| VIP2 Taker | 0.08% | 0.09% | 0.07% |
Verdict: OKX offers a better default maker fee (0.08%). Binance wins when using BNB for fee payment. At standard rates all three are roughly equal on taker fees.
For arbitrage: the difference between 0.10% and 0.08% on one side of a trade is $2 per $10,000. On both sides: $4. Over 300 trades per month at $1M volume, that's $1,200 in difference. At scale, pursuing VIP status on at least one exchange makes sense.
2. Liquidity and Order Book Depth
Liquidity is a critical parameter — it determines slippage and the maximum trade size without significantly impacting price.
| Pair | Binance (depth ±2%) | Bybit (depth ±2%) | OKX (depth ±2%) |
|---|---|---|---|
| BTC/USDT | ~$80–150M | ~$40–80M | ~$30–60M |
| ETH/USDT | ~$30–60M | ~$15–30M | ~$12–25M |
| SOL/USDT | ~$8–15M | ~$5–10M | ~$4–8M |
| BNB/USDT | ~$5–10M | ~$2–5M | ~$2–4M |
Figures are approximate — depth changes throughout the day
Verdict: Binance leads on liquidity across all major pairs. For trades up to $10,000, the difference is negligible. At $50,000+ position sizes, liquidity differences start affecting actual slippage meaningfully.
3. Number of Trading Pairs
| Exchange | Spot pairs | Futures pairs |
|---|---|---|
| Binance | ~2,000 | ~300 |
| Bybit | ~700 | ~400 |
| OKX | ~500 | ~200 |
Verdict: Binance leads on spot pairs. Bybit leads on futures (important for hedging positions in balance arbitrage). OKX has fewer pairs but all are liquid.
For arbitrage: more pairs = more potential opportunities. SpreadScan data shows Binance generates the most cross-exchange spreads with other platforms precisely due to its broader listing.
4. P2P Platform
P2P is a key feature for fiat and regional arbitrage.
| Criterion | Binance P2P | Bybit P2P | OKX P2P |
|---|---|---|---|
| Volume (fiat pairs) | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐ |
| Payment methods | 30+ | 20+ | 15+ |
| Number of offers | Maximum | High | Medium |
| Platform fee | 0% (buyer) | 0% (buyer) | 0% (buyer) |
| Trade speed | 5–20 min | 5–20 min | 5–25 min |
Verdict: Binance P2P is the clear leader in fiat operations — offer count, payment methods, and volume are significantly higher than competitors. Bybit P2P is a solid alternative and the second strongest market for CIS traders.
For P2P arbitrage: start with Binance P2P as the primary platform, Bybit P2P as second. OKX P2P is useful as a third platform for rate comparison.
5. Withdrawal Network Support
| Network | Binance | Bybit | OKX |
|---|---|---|---|
| TRC20 (USDT) | ✅ | ✅ | ✅ |
| ERC20 | ✅ | ✅ | ✅ |
| BEP20 (BSC) | ✅ | ✅ | ✅ |
| Solana | ✅ | ✅ | ✅ |
| Arbitrum | ✅ | ✅ | ✅ |
| Optimism | ✅ | ✅ | ✅ |
| Polygon | ✅ | ✅ | ✅ |
| Avalanche | ✅ | ✅ | ✅ |
| TON | ✅ | ✅ | ✅ |
| Total networks | 50+ | 30+ | 30+ |
Verdict: all three support the main cheap networks. Binance wins on total network count — useful when working with less common coins.
6. Deposit Confirmation Speed
Critical for transfer-based arbitrage — faster confirmation means less price risk.
Based on community data and trader reports:
| Network | Binance | Bybit | OKX |
|---|---|---|---|
| TRC20 (USDT) | 1–3 min | 1–2 min | 2–5 min |
| Solana | 1–2 min | 1–3 min | 2–4 min |
| Arbitrum | 2–5 min | 2–4 min | 3–6 min |
| BEP20 | 1–3 min | 1–2 min | 2–4 min |
Verdict: Bybit frequently confirms faster than Binance on most popular networks. OKX is slightly slower than both. For arbitrage, Bybit as the receiving exchange is often the optimal choice.
7. API Quality
| Parameter | Binance | Bybit | OKX |
|---|---|---|---|
| REST API rate limit | 1,200 req/min | 600 req/min | 600 req/min |
| WebSocket support | ✅ Full | ✅ Full | ✅ Full |
| API latency | ~10–30ms | ~15–40ms | ~20–50ms |
| Documentation quality | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ |
| Sandbox/Testnet | ✅ | ✅ | ✅ |
Verdict: Binance has the highest rate limit and best documentation. For developers building their first bots — Binance API is the easiest to learn. Bybit and OKX also have solid APIs, but with slightly higher latency and lower limits.
8. Security and Reliability
| Criterion | Binance | Bybit | OKX |
|---|---|---|---|
| Founded | 2017 | 2018 | 2017 |
| Security incidents | 2019 hack ($40M, reimbursed) | No major incidents | No major incidents |
| Insurance fund | SAFU ($1B+) | Protection fund | Yes |
| Proof of Reserves | ✅ | ✅ | ✅ |
| Regulation | Partial | Developing | Partial |
Verdict: all three are reliable for holding working capital. Binance was hacked in 2019 but fully reimbursed losses from the SAFU insurance fund — no major incidents since. Bybit and OKX have no history of large-scale breaches.
9. Mobile Apps
For manual arbitrage, a fast mobile app is critical — you often need to execute a trade quickly from your phone.
| Parameter | Binance | Bybit | OKX |
|---|---|---|---|
| iOS rating | 4.7 | 4.7 | 4.6 |
| Android rating | 4.2 | 4.5 | 4.3 |
| Interface speed | Medium | Fast | Fast |
| P2P in app | ✅ | ✅ | ✅ |
Verdict: Bybit and OKX have faster and more responsive mobile interfaces. Binance is more feature-rich but cluttered. For arbitrage where speed matters — Bybit's app is preferable.
10. Additional Features for Arbitrageurs
| Feature | Binance | Bybit | OKX |
|---|---|---|---|
| Futures for hedging | ✅ | ✅ | ✅ |
| Earn/staking for idle capital | ✅ | ✅ | ✅ |
| Copy Trading | ⚠️ Limited | ✅ | ✅ |

Frequently Asked Questions
Binance or Bybit — which is better for a beginner? Both work well to start. Binance has more pairs and better P2P; Bybit has a cleaner interface and faster confirmations. The best approach: register on both immediately.
Can I use just one exchange for arbitrage? Cross-exchange arbitrage requires at least two exchanges. Triangular arbitrage works on a single exchange. For meaningful arbitrage, two platforms are the minimum.
Is OKX better than Bybit for arbitrage? Depends on strategy. For CIS P2P — Bybit wins. For CEX-DEX and Copy Trading — OKX is stronger. For most strategies, both are roughly equivalent as the third exchange after Binance.
Do I need to verify my account on all three? Yes, mandatory. Without KYC verification, withdrawal limits are very low — making arbitrage practically impossible. Complete verification before starting to trade.
Which of the three has the lowest fees? At standard rates — roughly equal (0.10% taker). OKX offers 0.08% maker by default. Binance drops to 0.075% with BNB fee payment. Real discounts require trading volume for VIP tier.
