What Is Crypto Arbitrage and How Does It Work?
Arbitrage means taking advantage of a difference in price, or in payout, that exists at the same time in two places. In the crypto market these differences show up all the time, because each exchange has its own supply, demand and rules.
The idea behind arbitrage
Imagine the same coin costs $100 on one exchange and $100.40 on another. Whoever buys on the first and sells on the second at the same time captures the $0.40 difference, without depending on the price going up or down afterwards.
This logic works for several kinds of differences. What changes is where the difference shows up and how long it lasts. In efficient markets it tends to disappear fast, which is why anyone doing arbitrage needs speed and cost control.
The three most common types
- Price (spot) arbitrage: buying a coin on one exchange and selling it on another. It requires a balance on both and, sometimes, transfers between them.
- Funding arbitrage: being long on one exchange and short on another, on perpetual contracts, and collecting the funding difference. See what the funding rate is.
- Triangular arbitrage: swapping three coins in sequence within a single exchange, ending back at the starting coin with a little more.
Each type has different costs and risks. Funding arbitrage, for example, doesn't require moving coins between exchanges, which avoids withdrawal fees and transfer time.
Why it isn't easy money
If it were simple, the difference would vanish in seconds. In practice, the gain on each trade is small and is reduced by fees, by the gap between the buy and sell price (the spread) and by the chance that one of the legs doesn't fill.
Arbitrage reduces your dependence on the coin's price, but it doesn't eliminate risk. Partial fills, fees and exchange failures exist in every type.
That's why the result usually comes from volume, discipline and automation, not from a single big trade.
What you need to get started
- Accounts on at least two exchanges, with 2FA enabled.
- A balance on each exchange, since both legs need margin.
- A way to see the opportunities and execute orders quickly, by hand or with a funding arbitrage bot.
- Clear risk rules: amount per trade, leverage and when to exit.
If you'd rather automate, Multi Arbitrage monitors 14 exchanges, picks coins with the Prospector and opens both legs at the same time, always with keys without withdrawal permission.
A numerical example of each type
Price (spot): the coin costs $100.00 on exchange A and $100.40 on B. Buying 10 units on A and selling on B, the gross difference is $4.00. With 0.1% fees on each side ($2.00 in total), about $2.00 is left, and that's if the difference doesn't vanish while you execute.
Funding: a $1,000 position on each leg, with a net funding of 0.05% per payment. Each payment earns $0.50 before fees. The gain comes from repetition, which is why the payment history matters so much.
Triangular: you swap USDT for BTC, BTC for ETH and ETH for USDT. If the final amount is larger than the starting one after the fees on all three swaps, there's a profit. Because the margin is tiny, almost only bots can capture it.
Common mistakes beginners make
- Ignoring fees and looking only at the gross price difference.
- Going in with a large amount before understanding how orders behave.
- Leaving one leg open without watching the other.
- Thinking "no risk" means "no loss".
- Trusting anyone who promises a fixed return.

Frequently asked questions
Is crypto arbitrage legal?
Trading crypto on exchanges is allowed in many countries, but tax and reporting rules vary. Talk to an accountant about the obligations in your case.
Do I need a lot of money?
You can start with small amounts, but fees and minimum sizes weigh more on low amounts. See how much capital you need.
Which type of arbitrage is best for beginners?
Funding arbitrage is usually more accessible, because it doesn't require moving coins between exchanges. Even so, start small and understand the risks.
Start with $30 in credits
Connect your exchanges with keys that can't withdraw and let the bot work. You pay 30% of the profit, and only when there is a profit.
