I tried a betting bot only once and it lost for money. It might have been the case because it was a free script online. In the past I read a few success stories of people making money with betting bits, so I wanted to try it out myself. When using free betting bots you probably have to be very lucky to make money. Why would anybody give away his bot for free if it makes good money? As for subscription based models I haven't tried it, but would like to if they are legit. I am a little bit afraid now that it's a complete black box and someone takes advantage of my data. When it comes to automated betting then there could also be a bot that takes advantage of these strategies. Would be cool to see a survey to see how many people used a bot and how many made a profit of it.
