I’ve been looking into this topic for a long time and finally decided to understand it. Crypto arbitrage sounds like a way to make good money if you calculate everything correctly. The core is simple: you spot the price difference of the same coin across different platforms. Cheaper on one, more expensive on the other—that’s all the profit there is.

So why do these differences happen in the first place? It’s logical—each exchange has its own supply and demand, and prices update with delays. Local laws and market characteristics in different countries also play a role. That means the same coin can end up costing different amounts.

There are several types of arbitrage. The most obvious is inter-exchange. You buy BTC on one platform, transfer it to another, and sell it for more. It sounds simple, but you need to account for fees and transfer time.

There’s also an intra-exchange option—when you operate on one platform but take advantage of the price difference between trading pairs. For example, ETH/USDT is cheaper than if you calculate it through other pairs. You convert back and forth and earn a profit.

Triangular arbitrage is more complicated—it’s a chain of exchanges. USDT → BTC → ETH → back to USDT. All on one exchange, but through several steps. Speed and attention are required.

And there’s a regional method—when you buy crypto on a large platform and then sell via P2P in local currency with a markup. This is an even more complex option.

From a practical standpoint, it all starts with accounts on different exchanges. Most people use large platforms, but crypto arbitrage requires flexibility. The easiest way to top up your balance is with stablecoins—they’re stable and transfer quickly.

Next, you need to monitor prices. Doing it manually is brutally time-consuming, so people use bots or monitoring sites. This saves time and helps you not miss the moment.

The most important thing I understood is fees. They can completely wipe out your profit if you don’t calculate them. You need to consider fees for deposits, withdrawals, and the trading itself. Sometimes the price difference is smaller than what you end up paying in fees.

Speed is also critical. While you’re transferring crypto, the price can change. That’s why it’s better to use fast networks like TRC-20 or BSC. They work much more promptly.

A simple example: BTC on one exchange is $96,000, and on another it’s $96,100. It looks like there’s a $100 difference. But then you factor in the fees on both sides, the transfer time, and the risk that the price will drop during the transaction. In the end, there may be very little left.

That’s what worries me the most. Delays in transfers are a real problem. Withdrawal limits on some platforms restrict volumes. And there’s also the risk of being blocked due to regional restrictions or suspicions of fraud.

Crypto arbitrage is not a myth—people really do make money from it. But it’s not free money. You need a system, attention to detail, and an honest calculation of all expenses. I’d like to hear how it works in practice for people who have already tried it. Am I missing something?
