Mining wages in Africa
It depends on the source of the mine. If it is an "open pit mine", the investment is relatively small. The main investment is the wages of workers and the cost of transportation road construction. If the ore is deeply buried, the investment needs to be larger. In addition, the acquisition of mining license is also a part of the investment, and this is the main part. If there is no mining license, the others are always empty
To sum up, the main investment costs are as follows:1, workers' wages
2, machinery and equipment
3, transportation road construction and maintenance costs
4, mining license fees
5, and other costs

secondly, bitcoin has a perfect derivative route, which can accurately hedge risks. What about a shares? We have to buy up and wait for the harvest
bitoffer offers the strongest bitcoin option and is the best risk hedging tool in the spot
how to use options to hedge the fall risk of spot
for example, the current price of bitcoin is US $10000
if it goes up to US $11000, the spot profit is US $1000
if it goes down to US $9000, the spot loss is US $1000
if you open a put option hedging in bitoffer, the cost is only US $20. If bitcoin goes down from US $10000 to US $9000, the spot loss is US $1000, and the put option profit is US $1000, The two offset each other, your account does not have any loss, this is the charm of hedging
after opening the hedging mechanism, your account will make money if it goes up, and even if it goes down, because the risk has been completely offset.
the country with the richest mineral resources in the world is the country with the lowest income in the world. This country is Congo in Africa, where the people are very poor, but they are rich in minerals. Many people can't believe that in a country with 24 trillion U.S. minerals, the children here are starving
and the medical level here is very poor, so people here often get sick . But they are sick, but there is no good medical and health conditions to help them prevent and cure. Therefore, in this country, medical care is very backward, and their life expectancy is much lower than that of other countries. Many of the children here are stunted< br />
