I decided to understand cryptocurrency arbitrage as a way to earn money. Honestly, I have more questions than answers so far, but I liked the idea. The main concept is simple — cryptocurrency prices vary across different platforms, and you can profit from this difference. Buy cheaper there, sell higher here, and that’s your income. Why does such a difference even occur? It turns out there are several reasons. Different exchanges have varying numbers of active traders, prices update with delays, plus different countries have their own laws and demand. All this creates windows of opportunity for crypto arbitrage.

There are several types of arbitrage, and I haven't fully decided which one to choose yet. The first — inter-exchange. It’s straightforward: buy on one platform, transfer to another, and sell at a higher price. For example, Bitcoin is cheaper on one major exchange than on a competing platform — that’s the whole scheme.

The second type — intra-exchange arbitrage. Here, you don’t jump between platforms but work within one. You look at different trading pairs — maybe ETH is cheaper in USDT than ETH in BTC, and you convert one into the other, earning on the difference.

The third — triangular. This is when you perform a chain of exchanges on one exchange: USDT to Bitcoin, Bitcoin to Ether, Ether back to USDT. If the pairs are mispriced, you’ll come back with a profit.

The fourth type — regional arbitrage. You buy crypto on one platform, then sell it locally in another country via P2P, earning on the exchange rate difference and demand.

Where to start? First — you need accounts on several exchanges. That’s obvious, but which ones to choose — that’s the question. Second — fund your balance with stablecoins like USDT or USDC, which is the most convenient. Third — constantly monitor prices. There are special websites and bots that track the difference in quotes.

Fourth — and this is very important — calculate the fees. Many make mistakes here. Deposit fees, withdrawal fees, exchange fees — all of this can eat up your profit completely. If you don’t account for them, you risk going into the negative. Fifth — pay attention to network speeds. Some blockchains transfer crypto slowly, and during the transfer time, the price can move against you. I think for quick transactions, it’s better to use TRC-20 or BSC.

A simple example: suppose Bitcoin costs $96,000 on one major platform and $96,100 on another. You buy where it’s cheaper, transfer to the other exchange, and sell. Theoretically, you earn $100 minus fees.

The pitfalls are obvious right away. Fees are number one. They are really huge and can completely wipe out your profit. Transfer delays — while the crypto is in transit, the price can turn against you. Withdrawal limits on some platforms also restrict opportunities. And yes, there’s a risk of falling under regional restrictions or being suspected of something suspicious.

So, crypto arbitrage is a working scheme, but not without risks. I want to hear opinions from those who have already tried. Maybe I missed something?
