I've always wanted to understand how cryptocurrency arbitrage works… and now I've started studying this topic. So far, mostly theory, but I already understand some things.

Basically, the essence is simple: buy crypto cheaper on one platform, sell it more expensive on another, and profit from the difference. Sounds easy, but in practice, it's more complicated.

Why do prices differ at all? Well, first, different exchanges have different numbers of buyers and sellers. Second, prices update with a delay. And third, different countries have different demand and laws. This creates an opportunity window for those who understand it.

There are several types of arbitrage. The most obvious is inter-exchange. You buy crypto on one platform, transfer it to another, and sell it for a higher price. For example, BTC on one platform at $96,000, on another at $96,100 — that’s a hundred dollars profit (not counting fees).

Then there's intra-exchange arbitrage — when different trading pairs of the same asset on one exchange are priced differently. Like ETH/USDT being cheaper than ETH/BTC when converted. You convert back and forth and earn.

There's also a triangular option — exchanging one currency for another through several pairs on one platform. USDT → BTC → ETH → back to USDT. If prices don't match perfectly, there's profit left.

And regional arbitrage — buying on an international exchange in dollars, selling locally in your currency via P2P. The difference can be more significant here, but the risks are higher.

How to get started? First, you need accounts on several platforms (I've already done that). Second, fund your account — it's better to use stablecoins like USDT or USDC to avoid volatility. Third, monitor prices — there are special websites and bots for that.

But here’s the catch. Fees for deposits, withdrawals, and exchanges can eat up all the profit. You need to calculate everything in advance, or you risk going into the negative. And transfer speed — while crypto moves from one exchange to another, prices can change. For quick transactions, it's better to use TRC-20 or BSC networks.

There are also delays in price updates, withdrawal limits on some platforms, and the risk of blocks due to regional restrictions. All of this must be considered.

In general, I understand how cryptocurrency arbitrage works. But is it really possible to make money with the current fees? Maybe some of you have already tried? I’d be interested to hear the opinions of those in the know 🤔
