How Crypto Exchanges Work

A Guide to Exchanging Cryptocurrency

September 2, 2025

Whether you are investing in cryptocurrency, planning a big purchase overseas, or just looking to turn your digital coins into cash, cryptocurrency exchanges open the door to quick and convenient solutions. This guide will show you how these platforms work and help you pick a reliable exchange.

Exchanging crypto with 1tab is simple and reliable. You can convert USDT, BTC, or ETH into fiat, make international transfers, and pay invoices in more than 40 countries. Leave a request via our Telegram bot or talk to our manager if you need step-by-step support.

What is a cryptocurrency exchange

A crypto exchange works much like a regular exchange office, where you swap one currency for another. The main difference is that here, you exchange digital coins, such as USDT, ETH, and BTC, for fiat currency, like dollars or euros.

Crypto exchanges charge users a fee. The platform either fixes the fee or calculates it as a percentage of the exchange amount, typically ranging from 1.5% to 3%, and occasionally from 5% to 10%. Additionally, some exchanges may charge extra fees, such as withdrawal or network fees, which can add to the overall cost. It is important for beginners to check all potential fees to understand the final cost of their transactions.

Types of exchanges

Offline cryptocurrency exchanges typically have physical offices, often located in major cities in countries such as Georgia, Armenia, Kazakhstan, Ukraine, Israel, Spain, and Russia. These places look like modern bank branches, where you can complete your transaction and maybe even grab a coffee. Just bring your documents, or you can send a request online before your visit.

Online exchanges save both time and effort: these services are available from anywhere in the world, as long as you have internet access. Usually, small remote teams help process exchanges. Such exchanges do not require documents, but for some transactions, they may request verification.

Verification is a brief process to ensure the person making the transaction is who they claim to be. This can involve something simple, like taking a photo of your bank card and showing it in a chat with the exchange team.

Due to high market competition, online exchanges can offer more favorable exchange rates.

Online crypto exchanges differ in how they process user requests:

  • Manual. All operations are performed by an operator. If the exchange staff are busy, the process may take some time. Such services do not always operate 24/7.

  • Semi-automatic. The client submits a request via a special form on the exchange’s website, and an operator performs the subsequent steps. These platforms provide a balance between the convenience of automated services and the personalized approach important when exchanging large sums or in unusual situations.

  • Automatic. Operate without operators; all actions are performed by the system. This ensures fast and convenient exchanges. The user needs to specify the required amount on the service website, and in most cases, the desired currency will be received within a few minutes. Delays in transfer may occur in rare cases due to technical issues, which are usually resolved quickly.

How to Choose a Reliable Exchange

Before you pick a crypto exchange, take some steps to make sure it’s safe and reliable. Some exchanges aren’t trustworthy and may attempt to deceive you with attractive rates or fake reviews.

Be aware of red flags that signal potential scams. These include lack of contact information, pressure to act fast, promises of unrealistically high returns, and suspicious-looking websites. Identifying these signs early can help you avoid falling for scams.

So here’s how you can find a reliable online crypto exchange:

  • Check an exchange on aggregator websites. The most well-known is Bestchange. These platforms carefully verify exchanges, so if you find it there, it is a good sign. However, the absence of an exchange on such aggregators does not necessarily mean it is unreliable: not all quality services appear in these ratings.

  • Check the exchange’s rating and customer reviews on Google Maps and social media. For example, 1tab has a rating of 4.8.

  • Watch out for deals that look too good to be true. If most exchanges offer the rate of USDT to EUR at 0.85 to 0.87, but someone offers 0.90, it could be a scam. On 1tab, you’ll see the exchange rate and commission before you confirm your request.

  • When discussing a deal on Telegram, only use contacts from the official exchange websites. Scammers can create fake accounts by slightly changing the exchange’s username, so at a quick glance, it may look real. You can access the 1tab Telegram bot or chat with a manager directly from the website’s homepage.

  • Check that the exchange’s website uses a secure connection (https) and has a valid security certificate. This keeps your data safe. Also, look for clear contact details and customer support so you can get help if needed.

  • When exchanging cryptocurrency for cash, check if the exchange requires ID or provides clear instructions for receiving your money. If they skip basic security steps, it’s a red flag, and you should consider another service.

  • If you are exchanging cryptocurrency in a country where this activity is legally required to have a license, ensure the exchange holds one.

Online Exchanges vs. Cryptocurrency Platforms

Crypto exchanges make it quick and easy to turn your cryptocurrency into regular money, which is great for one-time deals. You usually don’t need to register, and you can exchange at a fixed rate right away.

Cryptocurrency platforms such as Binance, OKX, Kraken, and others, on the other hand, offer a wider range of functions, including trading various cryptocurrencies. It makes them attractive for those who want to trade actively and profit from price fluctuations. However, exchanges require registration and verification, and withdrawing funds may take more time.

Both crypto platforms and some online exchanges focus on cryptocurrency trading and allow you to swap one digital currency for another.

How does the exchange work in 1tab:

  1. To start an exchange, create a request on the 1tab website or through our Telegram bot.

  2. Specify the amount of cryptocurrency you want to sell, the desired fiat currency, and the city where you want to receive cash.

If you have questions or special requirements, contact our manager.

We’ll help you convert your cryptocurrency at a set rate and withdraw it in the currency of your choice, minus the transaction fee. You can get your money in the way that works best for you—sent to your bank card, delivered in cash by courier, or picked up at one of our partner offices.

In some countries you are required to present your identification. After that, we verify your crypto wallet to ensure the transaction is safe and secure. This verification process involves checking the wallet against databases of flagged addresses, such as those compromised by hacking activities or subject to international sanctions, helping to provide an additional layer of security.

Summary

Cryptocurrency exchanges make it easy to get cash or send money to your bank account, especially with online services you can use from anywhere. For beginners, it is completely normal to feel cautious at first. Master these checks once, and every future crypto cash-out becomes quick, fair, and stress-free.

When selecting an exchange, consider how you can withdraw your funds, the fees associated with it, and the supported currencies. Most importantly, check the exchange’s reputation, license, and user reviews to ensure your safety.

FAQ: How to Choose a Reliable Crypto Exchange

You can review aggregator websites like Bestchange, check ratings on Google Maps, and read customer reviews on social media.
