Investment and Gambling are but two sides of the same coin. Both can rake in money, and both could leave you penniless as well if you're not thinking straight. But what I believe is the biggest difference between the two is their purpose. Market Investment is made to make money initially, and Gambling, tho some may argue, is primarily there for entertainment. It's up to you to think about the worth and weigh of the two.
Totally agree!
In both cases, people should draw their own line which shouldn't be crossed. Investing constantly and just for the sake of doing so is pure gambling and the opposite.
Even in gambling, if you play smart and look for value, it could be considered an investment.
I also agree, investing and gambling is both about managing risks. You have money at hand which you want to put to use by either betting, gambling, trading or investing it. All of these things involve risk for which you are being rewarded by money from other people. You can either go long or short in investing, the same goes for sport bets. You can bet that your team wins or losses. Also in the eye of the government these are very similar things, because you need to pay taxes on them. If you know a lot about a company you can trade their stock, if you know a lot about the sport team, you can bet on their next game.
