Steembottracker.com isn’t even directly correlated to the amount of bids in each round. They only track the amount of bids sent through their site so doesn’t account for money sent outside of the site. On top of that, steem is in huge downtrend so when u send SBD for an upvote, your payout will get lower and lower each day while stream price is going down.
In conclusion your frustration is due to not being fully aware of how the site works. I’ve lost much more than you on single bids, it’s just part of the game.
