Two strategies, very different mechanics. Capital requirements, speed, risk profile, and passive income potential all differ — here's how to choose the right one for where you are right now.
When a price gap opens between exchanges, there are fundamentally two ways to capture it. You can move the actual coin — buying on the cheaper exchange, withdrawing it, and depositing on the more expensive one to sell. Or you can hold positions on both sides simultaneously using futures contracts, without moving any coin at all.
These are spot arbitrage and futures arbitrage respectively. Both are legitimate. Both are profitable. But they suit different traders, different capital sizes, and different risk tolerances. Understanding which applies to you is the first real decision in your arbitrage journey.
| Factor | Spot Arbitrage | Futures Arbitrage |
|---|---|---|
| Execution speed | Slow — 10 min to 2 hrs | Fast — seconds |
| Capital needed | Medium — needs funds on both exchanges | Medium — needs margin on both exchanges |
| Coin transfer required | Yes — blockchain withdrawal | No |
| Gap size needed | Large (2–5%+) to cover withdrawal fees and time | Smaller gaps viable (0.5–2%+) |
| Directional price risk | Yes — price can move during transfer | Minimal — delta-neutral by design |
| Funding rate income | None | Yes — collected every 8 hours |
| Liquidation risk | None | Low if managed — use conservative leverage |
| Best for | BTC/ETH on major exchanges with large gaps | Any coin with liquid perps and active funding |
| Difficulty level | Beginner-friendly in concept, tricky in execution | Moderate — needs basic futures knowledge |
The spot arbitrage workflow seems simple — buy cheap, sell expensive. But the coin transfer step is where most beginners run into problems.
BTC is $200 higher on Exchange B than Exchange A. At current price that's about 0.3% — but by the time you transfer, it might be gone.
You buy BTC at the lower price. You now own the asset but haven't sold it yet — you have directional exposure to BTC price.
You withdraw BTC to Exchange B. Depending on network congestion and chain choice (BTC mainnet vs Lightning), this takes anywhere from a few minutes to over an hour. During this window, you're exposed to price moves.
Once deposited, you sell. If the gap held, you profit. If BTC dropped during the transfer, you may have lost more than you made on the spread.
The blockchain network fee comes out of your profit. BTC mainnet fees can be $5–$30+ during busy periods. This alone can kill a small gap trade.
You cannot execute both legs simultaneously. You buy first, transfer, then sell — meaning price risk is always present between step 2 and step 4. In volatile markets, this window is genuinely dangerous. Spot arb works best when you already have funds pre-positioned on both exchanges, so no transfer is needed at all — but then you need double the capital to maintain that position.
Futures arbitrage eliminates the transfer problem entirely. Instead of moving a coin from one exchange to another, you hold two opposing positions simultaneously — one long (on spot), one short (on perpetual futures). Both positions cancel each other out directionally, but each earns from the pricing inefficiency.
ArbVertex detects: ETH funding rate on Bybit is +0.08% per 8 hours (annualised ~87%). Spot price on both exchanges is aligned.
Buy ETH spot on any exchange. Short ETH perp on Bybit. Both happen within seconds. Your net market position is flat — if ETH goes up, your spot wins and your short loses. They cancel.
Every 8 hours, Bybit pays you the funding rate because you're short and funding is positive. On $1,000 position at 0.08% rate: you collect $0.80 per cycle, or $2.40/day.
When funding drops back to near-zero, the edge is gone. You close both legs simultaneously. Total profit = sum of all funding payments collected minus open/close trading fees.
Position: $1,000 ETH spot long + $1,000 ETH perp short on Bybit
Funding rate: +0.1% per 8h (collected 3× per day)
Daily income: $1,000 × 0.1% × 3 = $3.00/day
After 7 days: ~$21 gross, minus ≈$4 in fees = ~$17 net on $1,000 (1.7% in one week)
There is no single right answer — but there is a clear pattern based on what most successful beginners do.
Start with funding rate arbitrage. It doesn't require timing a withdrawal window, doesn't expose you to price risk during execution, and generates income passively on a schedule you can predict. The main learning curve is understanding perpetual futures mechanics — which is worth learning regardless of your long-term strategy.
Consider spot arbitrage with pre-positioned capital. By keeping USDT ready on several exchanges, you eliminate the withdrawal step entirely — you can buy on Exchange A and sell on Exchange B simultaneously using what's already there. This is how serious spot arbitrageurs operate.
ArbVertex signals focus primarily on futures (funding rate + cash-and-carry) opportunities because they offer execution speed, passive income, and market-neutral exposure that spot transfers simply can't match at small capital sizes. Once you're comfortable with perpetuals, spot arb becomes a useful complement — not a replacement.
