Life can be considered as gambling, every action will create reaction, you gamble when you try to predict that. Trading is hard thing, I don`t trade for example, that is too hard for me, all that coins, numbers, who will scam whom. I didn`t even try to trade, cause its more gambling then dices, at least on dices I know my position and against whom I play, with trading I feel like I`m in dark, and I need to pick some coin and to have luck to make profit, that is gambling.
That is if you cannot mitigate risk. This is the reason why life being a gamble is nullified due to the risk mitigator function. If you cannot nullify risk then it is called gambling. If you can remove the risk factor then it is not a gambling.
Tell me how you lowering the risk in life? There is always a risk, when you plan to ask a girl to get out she can say yes or no, million stupid examples how life can be gambling cause you invest yourself, your body, energy, time, money, and some times you pick prizes, sometimes others do, life is full of up`s and down`s like gambling is, cause you nullify risk! Think about it and you will see for yourself.
