I think it's all coincidental and not because you are cursed or anything. In the world of trading, you win some and lose some. it boils down to how much you lost compared to what you won.
Indeed, sometimes we gain profits and sometimes we lossing our money in any investment market. I dont think cursed why we selling at bottom or buying at high, but its about stratey and make analysis. If we make a right analysis, i am believe that wont happen
