Arbitrage is the practice of profiting from a price difference for the same asset in two or more markets.
Why do crypto prices differ?
Each exchange runs its own order book. Local demand, liquidity and rules differ, so the same coin can trade at two prices.
How does crypto arbitrage work?
An arbitrageur buys the coin where it is cheaper and sells it where it is dearer. Many keep balances on two exchanges to avoid moving coins.
- Arbitrageurs hold balances on two or more exchanges.
- They buy the coin on the cheaper venue.
- They sell it on the dearer venue.
What costs and delays erase profits?
Each trade pays a fee, and a withdrawal adds a fee. The transfer waits for confirmations, and the price can move.
What are the main risks?
Arbitrage still carries risk. The gap can close before both trades finish, and a shown price is not a guaranteed trade.
- Price moves during transfer.
- Withdrawal freeze holds funds.
- Thin liquidity gives a worse fill.
- Exchange can fail and stop withdrawals.
How is it different from regular trading?
Regular trading on one exchange aims to profit from a price change over time. Crypto arbitrage aims to profit from a price difference between two venues.
It does not wait for the coin to rise, and the gain per trade is usually small.
