The time it takes to launch a white-label crypto exchange platform depends on several factors, including the scope of the project, the development team's experience, and the infrastructure in place. Typically, it takes anywhere from 3 to 6 months to fully launch a white-label crypto exchange platform.

This time frame can be reduced if the development team has prior experience in launching similar platforms and if the required infrastructure, such as servers and security systems, is already in place. On the other hand, if the platform requires custom development, has additional features, or lacks infrastructure, it can take longer to launch.

It's important to note that launching a crypto exchange platform is a complex process that involves multiple steps, including designing and building the platform, obtaining regulatory approval, integrating with payment systems, and setting up security systems. Each of these steps takes time, and any delays can impact the overall launch timeline.
