I’ve been interested for a long time in whether cryptocurrency arbitrage can become a real source of income, or if it’s just a theory. I decided to dig into it and share what I found.

The idea is simple: crypto arbitrage is buying an asset cheaper on one platform and selling it more expensively on another. It sounds logical, but in practice there are many nuances. Prices for the same coin can differ between exchanges due to different numbers of traders, delays in updating quotes, and regional demand factors.

There are a few approaches. The first is inter-exchange arbitrage: buy on one platform, transfer it, and sell on another. The second is operating within a single exchange, using the difference between trading pairs. For example, if ETH/USDT is cheaper than ETH/BTC, you can convert and profit from the difference. The third option is triangular arbitrage, where you carry out a chain of swaps through multiple pairs to return to your starting currency with a profit. And there’s also regional arbitrage: you buy crypto on a major platform and sell via P2P in another country in local currency.

To get started, you need accounts on multiple exchanges (I already have this), a balance in stablecoins like USDT or USDC, and constant price monitoring. Without tracking quotes, nothing will work. It’s also important to understand all fees—fees for deposits, withdrawals, and exchanges. If you don’t factor them in, it’s easy to end up losing money.

Speed is also critical. While you’re transferring crypto, the price can move in a worse direction. For fast operations, it’s better to use TRC-20 or BSC.

Here’s a simple example: BTC on one major platform costs $96,000, while on another it costs $96,100. You buy on the first, send it to the second, and sell. The theoretical profit is $100—but then you have to subtract the fees.

Here’s the catch. Fees often wipe out the entire profit, especially when the margin is small. Transfer delays can ruin everything. Some exchanges limit withdrawal amounts. And there’s also the risk of account or regional blockages (or account suspension) due to regional restrictions or suspicions of fraud.

Crypto arbitrage is a real, working mechanism, but it’s not a magic wand. You need speed, attention to detail, and an understanding of all costs. I’d like to hear from people who’ve tried it—does it work in practice, or am I missing something?
