Trading and Gambling are both same for me, as both are risky and waste of time, both involves risk of your money, which you can loose at any stage, so its better to stay away from both.
Yes, you are right they are both the same. Similar in that they both attempt to create a capital gain. Trading and gambling involve capital transfer without capital creation they are viewed skeptically, especially when their outcomes are unpredictable.
Trading is not a gambling in a sense that person can only lose some part of investment but in gambling chances of losing money become double. Trading required experience and if you have enough experience than you will have your invested money back with some profit while in case of gambling only luck matter, if you are lucky enough than you will win or lose your money.
If you believe on something like supertition or myth you might will always need luck on anything.
But if you want to be realistic then forget about luck or something like that.
And just stick on something visible such as you can maximize the winning chance in both trading or gambling by do some research, it is okay if you did not believe that certain gambling game can be analyzed , just the matter of different opinion.
