House edge games is really like that in any cases. After some so called beginners luck, people will think that gambling is just a piece of candy for profit taking hence they will continue more and will end up being busted.
Back to the topic, it's really happened in every side of the world. That's why it's obvious there will be more threads like this in every forum in the future.
