I decided to get a better understanding of cryptocurrency arbitrage… the theory has accumulated, but I want to understand how it works in practice.

Basically, the essence is simple: buy cryptocurrency cheaper on one platform and sell it more expensive on another, profiting from the difference. It sounds easy, but there are nuances. Prices for the same coin can vary significantly depending on the exchange — this happens because each platform has its own liquidity, different update speeds for quotes, and regional demand also influences.

There are several approaches to crypto arbitrage. The first is the classic inter-exchange: buy on one platform, transfer to another, sell. The second — within a single exchange, you can catch the difference between trading pairs. For example, if ETH/USDT is cheaper than ETH/BTC in equivalent, you convert and profit. The third option — triangular arbitrage, where you make several consecutive exchanges on one platform through different pairs until you return to the original currency with a profit. And there’s also regional arbitrage — buy crypto in one country, sell in another via P2P, considering local rates.

To start engaging in crypto arbitrage, you need accounts on several platforms, funded with a stablecoin balance (USDT, USDC). Then, monitor prices through sites like CoinMarketCap or specialized bots. The key point — always account for fees. For deposits, withdrawals, exchanges — all of this eats into profit. If you don’t consider it, it’s easy to go into the negative.

Here’s an example: suppose BTC is currently worth $81,760 on one major exchange, and on another, $81,900. Buy on the first, send to the second, sell. Theoretically, profit is $140. But subtract fees for withdrawal, deposit, spread on sale… and the margin becomes much smaller.

There are also pitfalls I see. Fees can eat up half of the profit. While transferring crypto between platforms, the price can change — especially if the network is slow. Withdrawal limits can hinder scaling. Plus, there’s a risk that the platform will block withdrawals if it considers activity suspicious.

For quick transfers, it’s better to use TRC-20 or BSC — they work faster than the main network. This is important because in arbitrage, time is money.

So, is this a real way to earn or am I missing something? I want to hear opinions from those who have already tried. Maybe there’s something I haven’t considered in my calculations.
