Well, I successfully beat any bots that were still in the game.
Thanks for creating the competition, but to be honest I expected more from it.
Expectation: battle of bots, background techniques, unknown technique for starting the first outgoing transaction...
Reality: starting fee 26% of balance, 1-2 bots
It was already clear that if you give a quarter of your balance as fee, then the probability that bots will beat the transaction is quite low.
And if the bot is really greedy, then it can turn 100% of balance into fee and then definitely win. LoL
