When you download a mod, do you really know what you're downloading? Ideally, the answer is yes, but what if something malicious is hiding inside - and what if the creator of the mod didn't even know something malicious was inside?

When deflation occurs, every single player becomes richer in a sense that their coins are worth more, and although it might not feel immediately different, it definitely does make a long term difference.
