Ive seen these bots for crash games before and they are not guaranteed to win everytime as it is gambling and there is risk involved with everytime you play.
I don't always go for gambling bots because they are not reliable and inaccurate in prediction but what I really like about they platform is the deposits bonus which is base on 3% daily so it will depends on the amount you deposit to determine what you receive as bonus which is use to place bet.
So if you deposit 1 ltc you will get 0.03ltc with this deposit bonus. But will you be able to withdraw the bonus amount right away or you will have to play through a few hundred times until you are able to?
This is what I do not like about these bonuses because there is a risk involved so you end up losing what you deposited.
