Idk what kind of black magic math did you use, but I just checked the internet calculator how much would you have after a year with 2% daily interest if you started with 1000 and it's around 8300 coins, not millions.
It doesn't happen that much, we have moderation, yesterday I saw two weird threads that looked more like bots than real people trying to abuse the system. We probably will rework coin system but right now we focus on LU page and progress is very promising. Original coin system allowed coin trading, it was designed that way so the richest users could reward new people who made an effort. Sadly, the richest users were more concerned about hoarding coins and participating in some pointless "who is the richest" competition than helping people so whole idea collapsed. Sure, there was me, Guz, Mime and probably few others who were helping new users but it was not enough. Trading system started to do more evil than good and so it was scrapped. I would boost you a bit, I saw your P5 angel, I really liked it, you could contribute nicely to P5, but for now just keep climbing.
