Yes I have... And I'm testing the players on there right now... I haven't had nearly the success though as @bumper.. the only one who has steadily given 3x or better return is @steembloggers (they have given me as high as 4x but on a still limited basis)...
It will take me longer to evaluate each of them because they aren't consistent in their payouts and some flat out underperform terribly. Also I haven't seen a spot that tells me what each of the metrics they use mean, so to some degree its trial and error for me because they are speaking a foreign language as far as I can tell... I'd love for someone to walk though each metric and let me test it out to see who is true... But as I said only @steembloggers and @bumper have performed at or above 3x in the tests I've run.
To me 3x is the minimum threshold (at this time) to make it worthwhile. Anything less is really not something I would be interest in.
Let me know if you hear anything or have one you think meets my 3x threshold or higher.
Have you used the click through send bid button on the steembottracker.com? I cant seem to get the automated version to work. I did manually send @bumper a transfer but cant seem to get the others to work. When i try to make them worm it says i dont have an account.
