You're right, but the more merit they get that may outweigh the activity points then they tend to be safer rank up than higher activity points than merit. I was one of the majority of users who when the merit system was introduced stuck at Hero rank, because I didn't have enough activity so I didn't get the 1000 merit airdop as one of the Legendary requirements.

You forgot to mention that you are actually a merit contributor who has a distribution history of 70% - 75% of the total merit you submitted (18K+ merit) on economy board, while you only have 9% - 14% distribution on the bitcoin board (3K+ merit). Then in Meta, you have send 1817 merit or 7.49% all the time but it will probably increase over time. I can find all that data on the merit dashboard.

One other fact, you have send 17,728 merit for the Legendary rank.
