How to choose a crypto exchanger
What to check when choosing a USDT exchanger in Kazakhstan: NBK licence, final rate, fees, limits, speed and support.
The lowest board rate is not always the best deal. Check an exchanger on five points.
1. Licence
Use only operators listed in the National Bank registry. A licensed exchanger is audited, verifies clients and answers to the regulator. The company name on the exchanger's website should match the registry.
2. Final rate, not the board
Exchangers show prices differently:
- some show the rate before a service fee and deduct it from the amount;
- some change the markup depending on the order size;
- some build everything into the rate.
So compare the amount you actually receive. The calculator does this by applying each exchanger's published tariffs.
3. Spread
The spread is the gap between buy and sell prices. A narrow spread matters if you plan to sell the USDT later, not just buy it.
4. Limits and payment methods
Check the minimum and maximum deal and the payment options: card, bank transfer, cash. Some exchangers give a better rate on large amounts.
5. Speed and support
See how quickly the exchanger sends crypto after payment and how to reach support. Good signs: clear terms on the website and a support reply within a business day.
