People who become interested in gambling only after hearing about gambling profits should discuss the highest risk, profit and loss of gambling. Newbies are welcome to gambling sites if they can accept maximum risk of gambling and can accept profit and loss. There are many new gamblers who don't have the least idea about gambling but they get very excited about gambling just by seeing other people's profits and without any thought they sign up to various gambling sites and start gambling. We all know the consequences of gambling without knowing anything about gambling. Accepting that it is difficult to take a decision in a new situation, but if we do not take a hasty decision, then it is natural that the decision will go against us. If a decision can be made patiently knowing everything beforehand then that decision will definitely go in favor of a gambler.
Yup, if the decision was made with a better understanding of the situation, chances to make something good out from your gambling participation is possible, though same thing with what you are saying, if there's no actual plans and no anticipation, you might end up losing a lot and the chance that you will keep on adding more is not by far.
It's your take and good understanding with how you take care of your gambling participation, else, unusual things might happen to you if you go far and get addicted.
