Taking gambling as an investment may help you manage your losses and winnings. This will help you to plan on how much money to stake with. It will also help you to avoid spending unnecessarily when you win.
Really, this is the first time I am reading something like this and at first, I was a bit amazed and wanted to get turned off but when I continued reading I saw that you have a very good point and all the while I have not thought of it that way, because if you take gambling as an investment, you will be concise in your dealings and spending at the same time, some of the things that affect many gamblers is the inability to follow lay down the principle that can help them to save their money while gambling.
But if gambling is taken as an investment, the player will be more proactive and deliberate in all that he does and as long as it making them profit it then ok.
But also fun gambling also is one thing we have to take into consideration since gambling is not a guaranteed source of income or investment.
