I don't know what "alpha" is and if you are not yet in legal age to gamble, maybe it's better that way. As soon as you start gambling you will have enough stress that will make get frustrated with gambling so don't rush it. For now, enjoy what you can while you are still young and if it can be possible just stay away from gambling. When you get in here, it will be tough to avoid it and you might even become one of the gambling addicts. I know it's nice to think of becoming a person of legal age to do all these things but trust me it's not.
