谢大牛盖章,反正也就扔点点钱进去争取搞点菜钱
I bought coffee JO last year with a price which was only $0.03 higher than the lowest price but sold after taking 10% profit. In January, it was doubled.
I spent a few weeks to study coffee plantation, production, price, etc and expected a price of $40. I almost put all money in buying JO stocks and option calls but didn't hold. Otherwise I don't need to trade anything this year after January. |
