Hope you get best of the answers but here my two suggestion point you should keep in your mind during use of such things .
First point is , don't use third party bot , in case if you have official option to make bet , for example at frrebitco.in you  have all facilities of auto bet like freebitco.in and another famouse sites have these options , that you need .At freebitco.in you can make easily autobet and also you can use manual script at pc and also you can find many types of the script at YouTube and Google for better gambling but I don't think that any script works for long term .
Second point is , don't leave the autobet for long term , always sit in front of your pc during betting , because any time can happen anything by the site algorithm ( as I faced big loss with even better stretagy of the gambling ) .
Once I lost continuously 23 bets at freebitco.in and almost same thing happened with me at another few gambling sites , so be ready toward anything wrong that may happen with you .
