Understand the opportunity before the trade.
Crypto prices can differ between platforms, currencies, payment methods and networks. Arbitrage is the practice of studying those differences and calculating whether a trade can remain profitable after every cost.
Arbitrage is about net profit, not the headline spread.
Suppose a trader can buy 100 USDT at 65 MZN and sell elsewhere at 75 MZN. The gross difference is 1,000 MZN. The trader still subtracts purchase fees, network fees, selling fees, FX costs, slippage and settlement risk. Only what remains is relevant.

No guaranteed profit
Arbitrage opportunities can disappear quickly. Payment reversals, frozen accounts, insufficient liquidity, price movement, network congestion and platform rules can turn an apparent spread into a loss. Never treat a price difference as guaranteed income.
