Obviously, investing would win in the long-run even if both involves risk. Gambling has long-term effects on a person especially when one gets addicted to it. If it becomes a habit, then the person would likely be bankrupt after a few months or years. Gambling has this illusion that no matter what you do, the odds are always with the casinos. You can never profit with gambling and it would only result to the destruction of your life. Investing on the other hand, even if it also involves risking your payment, has the potential of yielding you great amounts of profits with enough security on your payment compared to gambling.
