βοΈ Arbitrage Arbitrage
Buy a coin where it's cheaper and almost instantly sell it where it's pricier, keeping the price gap as profit. In crypto the same coin can sit at slightly different prices on different exchanges at the very same moment.
πͺ The simple version β same product, two prices
Picture buying bottled water cheaply at a wholesale store, then reselling it at a higher price at a beach kiosk. Same product, two markets, two prices β and you keep the difference. Crypto arbitrage is the same idea: the identical coin trades a little cheaper in one place and a little dearer in another, and an arbitrageur captures that spread. The key word is spread, the gap between the two prices at the same instant.
π Why does one coin have different prices?
There is no single global price for a coin. Each exchange runs its own order book with its own buyers and sellers, and liquidity is split across many venues. Regional demand, fees, and slow deposits or withdrawals all nudge the same coin to slightly different prices at the same moment. Arbitrage is the force that pulls those prices back into line, which is why the Bitcoin price looks roughly the same across the apps on your phone.
π― It bets on the gap, not the direction
Arbitrage is a market-neutral strategy. The profit comes from the gap between two prices at the same instant, not from guessing whether the coin will go up or down. You buy and sell almost simultaneously, so the coin's overall direction barely matters β what matters is that one price is higher than the other right now.
𧩠Common types in crypto
| Type | How it works |
|---|---|
| π Cross-exchange | Buy low on exchange A, sell high on exchange B |
| πΊ Triangular | Exploit mismatched rates among three pairs on one exchange (e.g. BTC β ETH β USDT β BTC) |
| πΈ Funding-rate | Profit from the rate gap between the spot price and perpetual futures |
| β‘ Flash-loan | Borrow and repay funds inside a single blockchain transaction to fund a DeFi trade β or it all reverts |
π Tether and other stablecoins are a classic target: when their price drifts from $1, arbitrageurs trade the gap and help pull the peg back.
π¨ Things beginners should know
- β±οΈ Execution risk β The gap can close before both trades complete; most chances vanish in seconds or less
- π§ Liquidity and slippage β You may not fill at the price you expected, especially on thin markets
- π§Ύ Fees and transfers β Trading costs and slow moves between exchanges can turn a paper profit into a loss
- π€ You're racing bots β Flash-loan and DeFi versions also carry smart-contract and regulatory risk
β FAQ
- Is arbitrage free, risk-free money?
- No. Most price gaps are tiny and close within seconds, often before both trades finish. Fees, slippage, and slow transfers between exchanges can turn a paper profit into a loss, and fast bots compete for the same gaps. It needs speed, capital on several venues, and real risk management.
- Why do the same coin's prices differ between exchanges?
- There is no single global price. Each exchange runs its own order book with its own supply and demand, and liquidity is split across many venues. Regional demand, fees, and deposit or withdrawal frictions nudge the same coin to slightly different prices at the same moment.
- Is there an 'arbitrage coin' I can buy?
- No. Arbitrage is a trading strategy, not a token. It can be applied to almost any asset that trades in more than one place, such as Bitcoin, Ethereum, or stablecoins like Tether.
