A white label cryptocurrency exchange platform refers to a ready-made software solution that can be rebranded and customized by a business or individual to launch their own exchange. The cost of building a white label cryptocurrency exchange platform varies depending on the vendor, and the specific features and customization needed. Typically, the cost includes licensing fees, hosting fees, software maintenance and support, and other services. A white label cryptocurrency exchange script provides an affordable and fast way to launch an exchange, as the core infrastructure is already built and tested. However, it is important to choose a reputable vendor with a proven track record in the cryptocurrency exchange industry to ensure the reliability and security of the platform.
