Whatever the one that we think is better or has more value, I believe that when you master your field art, failure would be far from you. There are people that will always prefer to use there money to gamble and gain result than using it to trade or even giving people to trade for them. We all have where we are good and where are not. For me, trading is more beneficial that just using my fund to play bet and waiting for result whather i will be lucky to make winning. Gambling is more of a lucky activity than just having the skill that will be more profitable like trading does. The more you gamble, the more experience you will have same way with trading too. Gambling is less if a skill activity.
There are many gambling games in which your skill does not matter at all and as such your results over the long term should be negative, however trading despite its seemingly random nature is all about your skill, if you are a good trader then it does not matter how low your starting capital would be, eventually you will become successful, it is because of this that when facing the choice of which one of those two options to pick people should become traders, as at least they have a real chance of making money if they become good enough at it.
