The process of exchanging Bitcoin and BTC for Visa Mastercard in KZT has a number of technical and regulatory features. First of all, Bitcoin is a decentralized asset, and each operation begins with sending funds from a wallet through the chosen network. At this stage, it is critically important to correctly specify the address, as an error makes a return impossible. The formation of the final amount depends on the market rate, the service fee, and the available reserve. Unlike stablecoins such as USDT or Tether, Bitcoin is not tightly pegged to the dollar, so the rate can change even during a single transaction. That is why the calculation is fixed before the operation begins. Depending on the conditions, the exchange can be implemented as an electronic transfer to a card or, less frequently, as a cash format through a specialized point. In the case of bank crediting, a payment mechanism is used where the money is credited directly to the Visa Mastercard in KZT, and the final conversion is performed in tenge. The service may impose additional requirements, including KYC, limit restrictions, and source of funds verification. This is standard practice for operations that have a banking and financial nature. Each transaction receives its status, allowing it to be tracked until completion.
