Mining in Africa

1. One T + 1, one T + 0, choose the second without hesitation
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.

6. African star diamond is processed from the same natural diamond kulinan“ Cullinan: discovered on January 21, 1905, at the pulemir mine, South Africa. It is pure and transparent, with a light blue tone, is the best grade of gem diamond, weighing 3106 carats. Up to now, it is the largest gem diamond found in the world
because the original stone is too large, it needs to be broken into small pieces. After kulinan was split, three skilled craftsmen worked 14 hours a day for eight months. A total of 9 large diamonds and 96 small diamonds were ground. The total weight of these 105 diamonds is 1063.65 carats, which is 34.25% of the original weight of kulinan. The largest one is called "African star I". It is shaped like a water drop and weighs 530.2 carats. It has 74 facets and is inlaid on the scepter of the king of England. The second largest one, called "African Star II", is a square, 64 sided, 317 carat, inlaid on the crown of the British Empire
it is now treasured in Buckingham Palace, UK<

in 1905, a 3106 carat diamond mine was discovered in South Africa, and the new transatlantic cable quickly spread the news around the world. At that time, experts in the gem instry estimated that the value of the mine was as high as $7.5 billion. As South Africa was a British colony at that time, it was agreed that it should be shipped to London for King Edward VII. This unparalleled treasure has aroused the imagination of jewelry thieves all over the world. The relevant personnel spent several months thinking about how to ensure the safety of transportation. Finally, the London police office decided that the best principle was "the simpler, the safer.". The eggplant sized diamond was mailed in an unmarked package and appeared in the royal mail bag at Buckingham Palace a month later. On February 10, 1908, the giant drill was cut into several large pieces for processing. The total amount of the finished proct is 1063.65 carats, which belongs to the British royal family. The largest diamond is named "kulinan 1", also known as "African star", weighing 530.02 carats
speaking of the king of diamonds, "star of Africa" is well deserved. This world's largest gem grade diamond was discovered in January 1905 at the pulemir diamond mine in South Africa. At that time, it was called "kulinan" diamond. It is a diamond with incomplete crystal. Its color is colorless and transparent, without any defects, and its texture is excellent. It weighs 3106 carats“ The name "kulinan" comes from the name of the general manager of the mine at that time
in January 1905, fredwell, the supervisor of the diamond mine in pulemir, South Africa, was walking in the mine. He found a shining object in the reflection of the setting sun. At first, he thought it was a glass bottle falling in the mud. When he lifted it up with a cane and scraped off the mud, he was shocked. He could hardly believe his eyes. It was a diamond as big as a fist. He got a reward of ten thousand dollars because he got Qibao
the largest diamond in the world was bought by the British government for 750000 US dollars and shipped to England. In 1907, it was presented to King Edward VII as the king's birthday gift at the age of 66. Later, the huge diamond was sent to the Dutch capital for cutting and grinding. After several months of research, analysis and evaluation, many experts unanimously decided to divide the diamond into three big diamonds. Experts carefully studied the direction of its division, and opened a quarter inch gap in the direction of its division. On the afternoon of February 10, 1908, the king of England personally selected josephich brothers, the famous Dutch diamond segmentation expert, to be responsible for the division. Accompanied by a team of consultants at the scene of segmentation, we will study the changes at any time, and ask a doctor and two nurses to escort the scene. If there is any deviation in their estimation, improper force or wrong angle, the diamond may split into tens of thousands of pieces of gravel, and then the future and reputation of segmentation experts will end. At this time, the air in the room was very tense. The segmentation expert put the steel blade straight into the predetermined gap, raised the wooden hammer and hit the back of the blade fiercely. The blade was broken! The giant drill didn't crack at all. At this time, the segmentation expert was sweating, but he was still calm. When he raised the wooden hammer again, he was so nervous that he even felt difficult to breathe. The segmentation expert hammered the newly replaced knife vigorously, and the diamond was completely divided into three pieces according to the plan. At this time, the segmentation expert also immediately fainted on the ground, and then recuperated in the hospital for a long time before returning to normal
after the giant diamond was divided, it was cut and ground on March 3 of the same year. Three experts worked 14 hours a day and spent eight months to grind the largest four diamonds
"kulinan No.1" is pear shaped and the heaviest one, weighing 530.2 carats. It was later inlaid on the scepter of the king of England. This giant diamond is called "the star of Africa". It has 74 facets
"kulinan second" is a square, weighing 317.4 carats, which is decorated on the crown of the king of England
"kulinan third" is pear shaped and weighs 94.4 carats. It is set on the top of the Queen's crown
"kulinan No.4" is square and weighs 63.6 carats. It is made by dividing the smallest diamond into two parts, namely "kulinan No.3" and "kulinan No.4". It was decorated on the edge of the Queen's crown
"kulinan" diamonds are cut into nine large diamonds and 96 small diamonds, which are used for crown, scepter and other decorations. The remaining five diamonds are: the fifth is heart-shaped and weighs 18.8 carats; The sixth is pointed and weighs 11.5 carats; The seventh is pointed and weighs 8.8 carats; The eighth is rectangular and weighs 6.8 carats; The ninth is pear shaped and weighs 4.39 carats. In addition, there are 96 small diamonds, which have been scattered all over the world, weighing 8 carats. The rest is a pile of very small stones, weighing 9.5 carats
this huge 3106 carat "African star" raw stone has been cut and ground into 105 diamonds, 1064.26 carats in total, and 9.5 carats of gravel that can not be cut and ground. The weight of the finished proct only accounts for one third of the original stone, which shows that the consumption of grinding the original stone into a diamond is very large
14 years later, in 1919, not far from the discovery of the "African star" diamond in the same mine, an incomplete diamond with a weight of 1500 carats was found, which should rank second in the world by weight, and must be named separately. However, people have studied the characteristics of this diamond, according to its crystal characteristics, fracture shape and other characteristics, It is believed that it belongs to the same crystal as the "star of Africa" discovered in 1905, but the "star of Africa" was discovered first after splitting, so it is not named again. In other words, if the "kulinan" of "African star" did not split, its total weight should be more than 4606 carats.

9. Africa is a rich continent with the largest reserves and output of gold and diamond in the world, as well as copper, iron, uranium and other metal minerals. South Africa is the country that proces the most gold in the world, Guinea is the country that proces the most bauxite, and Zambia is the country that proces the most copper. However, oil is the largest mineral output in Africa, Nigeria, Libya, Algeria and Egypt have become the major oil exporting countries. Africa's proven oil reserves rank the third in the world, second only to the Middle East and Latin America. Due to the underdeveloped instry, the oil proction is far greater than the consumption, and most of them are exported abroad, mainly to Europe.

10. Ha ha... Many African countries can privately mine diamonds, but they are only small-scale deposits! I haven't heard of any large diamond mines facing indivials
what should we pay attention to? Pickaxe, shovel and small mesh sieve are necessary. Do you want tents and mosquito repellents? Do you want food or water? We g out diamonds. Do you want guns or ammunition? Do you want an SUV on the road?
