Paper and silver make money slowly. Silver is not bought and sold by the catty, but by the gram. 10 Jin is 5000 grams. 6. 18 yuan per gram, * * * invested 309,000 yuan.

Profitability: (6.9-6. 18)*5000=3600.

Profit rate: 3600/30900 *100% =11.65%.

Is it too much to invest more than 30 thousand and make a profit of 3600?

If you speculate in futures, according to the deposit of 10%, the transaction amount of 30,000 yuan (total investment) only needs to pay 3,000 yuan.

In this case, if you earn 3600 yuan, you only need to invest 3000 yuan. The yield is 1 1 1.65%.

So futures make money much faster than silver.

Futures have other advantages over silver, that is, they can make money by going up and down. Paper and silver can only make money if it goes up, and there is no chance to make money if it goes down. But the benefits are accompanied by risks, and there are risks when there are benefits. No master can earn 100% of the money.
