These points highlight some fundamental differences between Bitcoin and Pi. It's worth noting that Pi is still an emerging project, and its features and characteristics may evolve as it progresses. It's advisable to conduct thorough research and exercise caution when considering any cryptocurrency investment.
These are not fundamental differences, they are all flaws in the project at this point in time. I don't see the point at all in comparing bitcoin, which can show some result, and this project, which has nothing. All the advantages of PI are only on paper for now or they are planned for some foreseeable future.
No centralized project will ever be able to overtake bitcoin or compete with it somehow.
