During trading, you need to think with your head and make your own decisions. In case of loss, it will not be so offensive, you can learn from your mistakes. During the investment, you do not need to bother with the choice of strategy and the miscalculation of profit options.
Exceptionally you are wrong because for both there is risk involved, because before investing and trading you have to find all possible ways, whether you will make the profit from it or not. But when compared to investment, trading will be in our control.
But if you look for higher returns on your investment, then definitely you have to bear the losses, because when you do invest, the control of your money will be not our hands.
