I just don't get the logic of these type of people that offers bots to have a higher chance of winning. If you're winning plenty of amounts, why bother selling it?
Let's just say that you found an exploit to a casino or lottery. Would you share it with anyone, even those who are close to you? I think not.
A reason that you want to share it with others isn't that convincing. You sell it without even proof of the website you've played.
I think that is because the bot is not working anymore for them, so they decide to sell it to people and hope some people will interest in the bot and buy it. If I were him, I would not sell the bot, but I will do it for myself, and I will try to get more and more wins before the casino realize that I used the bot. But even if he gave much proof to us, it doesn't mean that the bot will work for the buyer because I think the bot needs to use a different method to get the win. I don't think it will be easy for the buyer to follow every step he gave to win.
Maybe yes or also the bot is not working the way OP entice their possible client, if this bot can bring that amount for sure anyone who have it will not sell it out or will not exposed this knowing that gambling site owners are also here which can easily track down how this bot works and easily change or adjust to prevent sucking their business. It's a business that design to earn and not a charitable place to simply withdraw money.
