Understanding Bitcoin Arbitrage
Bitcoin arbitrage—often called "price discrepancy trading"—refers to exploiting price differences for the same cryptocurrency across exchanges. This involves buying low on Exchange A and selling high on Exchange B to pocket the profit.
Example Scenario:
- Exchange A lists BTC at $5,800
- Exchange B lists BTC at $6,000
Two Profit Methods:
- Deposit $5,800 into Exchange A → Buy BTC → Transfer to Exchange B → Sell for $6,000 → $200 profit.
- Deposit 1 BTC into Exchange B → Sell for $6,000 → Use funds to buy 1.035 BTC on Exchange A → 3.5% more BTC.
Common Challenges
- Fiat deposit/withdrawal limits
- Execution delays (price gaps close before trades complete)
- Transaction fees (exchange + blockchain network costs)
How to Execute Arbitrage
1. Avoiding Fiat Restrictions
Use crypto-to-crypto trading pairs (e.g., BTC/ETH) on platforms like Poloniex or Bitfinex. Benefits:
- No fiat verification delays
- Lower/no deposit/withdrawal fees

2. Solving "Time Gap" Issues
Single-Leg Arbitrage (Risky)
- Requires 5+ steps (deposit → trade → withdraw → repeat)
- Slow: Takes ~30 minutes → Price gap may disappear
Dual-Leg Arbitrage (Recommended)
- Pre-fund both exchanges with BTC and ETH.
When Exchange A shows 1 BTC = 15 ETH and Exchange B shows 1 BTC = 10 ETH:
- On Exchange A: Sell 1 BTC → Get 15 ETH
- On Exchange B: Buy 1.5 BTC with 15 ETH → 0.5 BTC profit
Advantages:
✅ Near-instant execution
✅ No withdrawal/deposit delays
✅ Hedges against price volatility
3. Managing Fees
- Ensure the price gap > total fees (typically 0.4% for two trades).
- Example: If Exchange A (0.05 BTC/ETH) and Exchange B (0.048 BTC/ETH) show a 4.16% gap, a 3.6% profit remains after fees.
Choosing the Right Exchange
| Factor | Why It Matters |
|--------|----------------|
| Security | Avoid platforms with history of hacks/scams |
| Liquidity | Deep markets minimize slippage |
| Trading Pairs | More pairs = More arbitrage opportunities |
Top Exchanges for Arbitrage:
- Binance (Low fees, high liquidity)
- Bitfinex (BTC/USD pairs)
- OKX (Multi-leg support)
Selecting Trading Pairs
- High volatility = Larger price gaps
- Established coins (BTC, ETH) = Faster transfers
- Avoid illiquid altcoins (high slippage)
