There are a few reasons why some people believe that the slowness of the Pi Network mainnet launch is a sign of a scam.Lack of transparency: The Pi Network team has not been very transparent about the development of the mainnet. They have not released a roadmap or timeline for the launch, and they have not provided much information about the technical challenges they are facing.Delays: The Pi Network mainnet launch has been delayed multiple times. The original launch date was set for early 2021, but it has since been pushed back to October 2023.Centralization: The Pi Network is still very centralized. The Pi Core team has a lot of control over the network, and they have not yet released the code for the mainnet to the public.These factors have led some people to believe that the Pi Network team is not actually working on a mainnet, and that they are simply scamming users.However, there are also some reasons to believe that the Pi Network is not a scam.The Pi Network team is made up of experienced developers. The Pi Core team includes developers who have worked on other successful cryptocurrency projects, such as Stellar and Ripple.The Pi Network has a large and active community. There are over 47 million Pi users worldwide, and the Pi Network community is very active on social media.The Pi Network has made progress on the mainnet development. The Pi Core team has released a number of testnets, and they have said that they are close to launching the mainnet.Overall, it is too early to say whether or not the Pi Network is a scam. The slowness of the mainnet launch is a red flag, but there are also some reasons to be optimistic about the project.It is important to note that the Pi Network is still under development, and there is no guarantee that it will be successful. Users should be aware of the risks involved before investing in Pi Network or any other cryptocurrency.
