I've been wanting to understand this for a long time… so far only the theory, but it's already interesting. Here's what I’ve learned about crypto arbitrage.

The essence is simple: the same cryptocurrency can have different prices on different platforms. You buy cheaper here, sell higher there, and that’s how you make a profit. Why does this happen? There are several reasons. First, each exchange has its own supply and demand. Second, prices update with a delay. And third, different countries have different laws and demand for assets.

There are several crypto arbitrage strategies, and I haven't decided which one to choose yet. The most straightforward is inter-exchange arbitrage. You just buy on one exchange and resell on another. For example, buy BTC on one platform, transfer it to another, and sell at a higher price. There’s also an intra-exchange option — when prices for the same currency differ across different trading pairs on the same platform. For example, ETH/USDT is cheaper than if you calculate through BTC. You convert and profit from the difference.

Then there’s triangular arbitrage — making a chain of exchanges on one exchange. Like USDT → BTC → ETH → back to USDT, with a profit somewhere in this chain. Plus, regional options — buying crypto on an international exchange and then selling in local currency via P2P in another country.

How to get started? You need accounts on several major platforms. Then deposit money, preferably stablecoins like USDT or USDC — they’re more convenient for maneuvering. Next, you need to catch the right moment — monitor prices through special websites or bots. This is important because the window of opportunity can be very narrow.

But there’s a catch. Fees. They can completely eat into your profit if you don’t account for them properly. You need to consider deposit, withdrawal, and trading fees — everything. Plus, speed matters. While crypto is transferring from one exchange to another, prices can change against you. I’ve noticed that networks like TRC-20 or BSC are faster than others.

Here’s a simple example. BTC on the first platform costs $96,000. On the second, it’s $96,100. You buy at $96,000, send it to the second exchange, and sell at $96,100. Theoretically, you make $100. But minus fees — and you might end up with a loss. That’s why it’s crucial to calculate everything carefully.

There are also additional risks. Some exchanges limit withdrawal amounts. Regional restrictions may arise. Or they might block your account altogether if the system suspects suspicious activity. Transfer delays are another pain point.

In general, crypto arbitrage is a viable way to earn money, but it’s not as simple as it seems at first glance. Am I missing something? I’d like to hear the opinions of those who have already tried. Maybe you have some tips?
