My best guess is that I started the year slightly below 2 million. If that's the case, the writing on the FAQ is inaccurate. It says that only gains above 2 million dollars will count toward leaderboards, when it should say that a player won't appear on a leaderboard if they don't begin the year/month/week at or above 2 million. I want on the weekly board the first week or the year, but have been ever since, which supports my theory about the two million threshold.
