I have used Bitzua services many times. I really like everything. This cryptocurrency exchange service has become my permanent choice, as it offers a favorable exchange rate. I sold my BTC and received cash, most importantly, at the best rate. The service is top notch, from the application to the completion of the transaction. The exchanger works smoothly, the employees are pleasant and understand their business, transactions are fast, punctual, accurate and safe. Among all the cryptocurrency exchange services, I prefer this one, thanks to its convenience and efficiency of operations.
