I remember a project long time ago that I have invested money that I've earned and it was high in value now if I can look back at that time. It may not that be much on those years but I have believed about that "earning" while doing some activities is a good feature. But it didn't took long time when this "trade to earn" or "trade to mine" feature of a project because eventually they've made an exit scam. They have rug pulled without having to say anything and everything was deleted. I am not saying that this is what PI is trying to do but it made me remember that moment and so with those people in this community of PI, I'll just say good luck to all of you.
