I decided to look into something new for myself. Honestly, it’s still just a theory so far, but cryptocurrency arbitrage sounds like a real way to make money. The idea is simple: you buy crypto cheaper on one platform, sell it for more on another, and earn profit from the price difference. It seems straightforward—so why does it actually work?

As it turns out, the prices for the same coin can differ significantly between exchanges. This happens because there are different numbers of buyers and sellers everywhere, plus delays in updating quotes, and of course different laws in different countries. Pretty interesting, actually.

Now, onto the types. I was also a bit confused about which one to choose. The first is inter-exchange arbitrage. You buy a coin on one platform, transfer it to another, and sell it there. For example, you bought ETH on a major exchange, sent it to another—and there’s your difference. The second option is intra-exchange arbitrage, where you operate within a single platform using the difference between trading pairs. Like if ETH/USDT is cheaper than ETH/BTC, then you convert and profit.

There’s also triangular arbitrage, which is when on one exchange you exchange one currency through several pairs. USDT to BTC, then BTC to ETH, then back to USDT. On paper it sounds like a money-printing machine. And regional arbitrage is when you buy crypto in one country and sell it in another via P2P, using differences in exchange rates.

Where should I start? Well, accounts on different exchanges are the basics—I’ve already done that. Next, you need to fund your balance, preferably with stablecoins like USDT. After that, you have to constantly monitor prices—there are special websites and bots for that. But most importantly, don’t forget about commissions! This is critical. You need to factor in commissions for deposits, withdrawals, and exchanges. Otherwise, you might end up in the red instead of the green.

One more point is speed. While your crypto is being transferred from one exchange to another, the price can change and your profit can vanish. That’s why you should use fast networks, like TRC-20 or BSC.

A real-life example: BTC on a major exchange costs 96,000 dollars, while on another platform it’s 96,100. You buy on the first exchange, transfer it, and sell on the second. The theoretical profit is 100 dollars minus all commissions. That’s all there is to cryptocurrency arbitrage.

But there are pitfalls I can see. Commissions—they can wipe out your profit entirely. Transfer delays—the price could drop while your money is on the way. Withdrawal limits—not all exchanges let you withdraw as much as you need. And there are also risks of account blocks due to regional restrictions.

So is cryptocurrency arbitrage really a thing, or am I missing something? I’d like to hear what people who’ve tried it think. Maybe I’m making a mistake somewhere in my calculations?
