I've long noticed that the same coin can have different prices on various platforms.

This caught my interest — can you actually make money from this?
I started digging and found out that this scheme is called inter-exchange cryptocurrency arbitrage.

The essence is simple: you see that BTC is cheaper on one platform than on another — buy there, sell here, and make a profit.
But it turns out, it's a whole science with different options.

Why do these differences even occur?
It's simple — each exchange has its own demand and supply, plus prices are updated asynchronously, and different countries have different regulations and purchasing power.

I read about various ways to use this.
The most obvious is inter-exchange cryptocurrency arbitrage, where you just transfer crypto from one platform to another and sell it at a higher price.
But there are also more clever schemes.
For example, you can catch the difference between trading pairs within one exchange — when ETH/USDT is cheaper than through other pairs.
Or get really tricky with triangular arbitrage, jumping between three or four currencies on one platform and returning with a profit.

There's also a regional option — buying on a major exchange in dollars, then selling locally via P2P in the local currency.
That often has a big spread.

From a practical standpoint, it all sounds logical, but there are nuances.
You need to open accounts on several platforms, fund them with stablecoins like USDT, constantly monitor prices.
There are bots and websites for this, but you need to learn how to use them.

The most important thing — don't forget about fees.
Deposits, withdrawals, exchanges — all eat into your profit.
If you miscalculate, you could end up with a loss instead of a gain.
Plus, speed is crucial — while the money is in transit, the price can change and ruin everything.
That's why I heard that for quick transfers, it's better to use TRC-20 or BSC networks.

Here's a simple example from theory:
BTC on one platform is $96k, on another $96.1k.
Bought at 96k, sent, sold at 96.1k.
Minus fees — you get around $100 profit.
It sounds small, but if scaled up…

But there are pitfalls too.
Withdrawal limits, transfer delays, and the risk of getting blocked if the platform suspects something strange.
Overall, inter-exchange cryptocurrency arbitrage requires constant attention and quick decisions.

I'm curious — does this really work, or am I missing something?
Maybe some of you are doing this?
Waiting for advice, especially about what amounts to start with and which exchanges to choose 🤔
