When someone said, contact me for free bot, it's like a scam attempt for me. Would anyone share or give their hardwork for free? When they have found best strategy for them to use and they just give it for free to all people? Doesn't make sense.

Your bot said it learned from history of bet and then trying to copy what the history happened, which is just coincidence that bot still on profit, we know we can't rely on history while we gambling.
