Couldn't tell you, but I know IRL friends with what I'd consider small followings (sub 10k) and they make over a hundred per payout cycle. I've also seen larger accounts post their payouts and have seen multiple in the $10k+ arena. Until that program dies or the rates drop significantly, they're very unlikely to move.
You also have the class of folks that run Bitcoin-related businesses so they are unlikely to move due to the network effects X enjoys.
