A bet is an agreement with other person. The agreement is that the one who loses the bet will owe the winning person. If the losing person does not pay the winner, then he is breaking that agreement.
In a courtroom, anyone who breaks an agreement is considered guilty. Being guilty in front of God is considered a sin.
Gambling is a fool's venture and it is always a bad move, even if you occasionally win.
Provident investment counsel is available at any SEC licensed securities broker. They will ask you what your plans are, what you expect, what risks you are prepared to endure, and much more.
If it all seems rather complex and involved, it is that way for a good reason. Ask for clarifications until you understand the program clearly.
Then, and only then, invest.
