Not sure if this helps :) but technically speaking, you're the 1,000,000th user, since @miners has id=0 (check https://steemd.com/@miners) I actually discovered this account a few days ago, and based on the number of followers (I'm the 2nd! follower), not many people know this. Of course, id=1,000,000 looks still better, but 999,999 sounds also great. Congrats :)
