It's almost the same , for me personally it's the same. In trading you are trying to predict the market moves as in gambling you are trying to predict an outcome of a sport event. There's no much difference in both situations. Surely in trading you have more news to back your choice but in the end you are still relying on luck to come out victorious.
I agree with you. Both activities are similar in some aspects. In both you need to predict the results of the market or of the numbers, in both you can make a lot of profit and become rich, in both you can work at home on internet.
I prefer gambling, because I know how to do it better, but I know trading is profitable too and many forum members are earning money this way.
I am agree with your first point, that both have similarity because doing the trading and playing the gambling have a same way, we can judge it and do it.
But i am disagree with your second point that both are profitable ways for many time, I accept it trading can be profitable but it need long time, it is hard we earn profit on everyday. And secondly, gambling can't be a profitable and help us to become rich, because i have play gambling since last 2 years, but still i can't see anyone who become rich from only behalf of gambling.
