The era of mobile mining is aleeady fading out and I Pinin particular has been around for many years now even before many of these projects that have launched and still trending in the market. Pi really wasted so much time before they decided to launch which I think the waiting time was too long and many holders had already sold their pi token because they thought the team will never launch the project.
Pi is a good project to those that had mined it years before now and I think many miners would start becoming patient so they don't lost their mined coins just because the project has not launched.
