The cost of developing a white-label crypto exchange can vary widely based on several factors. These factors include the platform's features, licensing fees, development costs, and the level of customization required. From my market research, the cost can range from $10,000 to $20,000, but this can vary significantly depending on your specific requirements and the development company you choose to work with. It's best to contact a reputable white label crypto exchange development company to get a customized quote tailored to your needs.
