Old cat virtual currency

1. blockchain is a kind of distributed technology, which can be specifically composed of technologies under the network. At present, ordinary people can invest in two directions. One is to invest in stocks of blockchain enterprises, which has certain risks. Indivials can invest in virtual currency, which is similar to bitcoin, according to what they are familiar with. However, they need to choose a reliable old platform, For those who have a long history and have a good reputation, you can take a look at AEX and fire coin. For those who have a long history and have long-term financial management, you can choose AEX financial supermarket

2. 1. Using bitcoin mining machine to obtain bitcoin
mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao
3. Reward for bitcoin
with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security

3. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. Fire coin network, okcoin and coin security network are the three major bitcoin trading platforms in China. Due to the high risk of bitcoin trading, it is recommended to choose carefully for users with immature investment experience

The gold and silver commemorative coins issued by the people's Bank of China should use the legal unit of measurement "gram, kilogram, kilogram" according to the measurement Law of the people's Republic of China. After the 2015 edition, the weight of the Panda Gold and silver coins is no longer marked on the face. In other words: no longer in accordance with international practice! Goodbye, oz

according to the requirements of the measurement Law of the people's Bank of China in 2014, the gold and silver coins issued by the people's Bank of China should use the legal measurement unit of "gram, kilogram, kilogram". Since 2015, the newly issued panda coins will no longer be marked with weight. Panda Coin before 2015 will be the best in ounces! In the early 1980s, the rare old cat coin has a long history and has a good collection reputation< The characteristics of the early cat coins are as follows: (1) limited by historical conditions and controlled by the state, the actual casting amount of the old cat coins in the 1980s is very small

each old cat coin in the 1980s has a history of more than 25 years. Limited by the domestic gold consumption capacity and proction technology at that time, although the circulation was not announced at that time, the actual casting quantity and existing quantity were extremely rare< (2) in the early stage, cat currency was mainly exported to create foreign exchange, and its domestic stock was extremely scarce

when panda coins were issued in the early stage, they were mainly sold abroad to create foreign exchange and support the national economic construction because of the low level of people's livelihood and economy at that time and the low consumption ability to buy gold< (3) the volatility of international gold prices in the 1980s and 1990s led to a large number of old cat coins melting into gold for high-level cash out

in the 1980s and 1990s, the international gold price was volatile, and foreign Giant Panda Coin agents and investors began to cash in the cat coin as gold, resulting in the rarity of the old Panda Coin in the world< (1) 82 golden cat 1 / 4 ounces, the first set of panda gold coins in China

(3) adding "starlight" stealthily has been praised by foreign countries all the time

① the 83 year panda gold coin has two small starlight patterns. At first, there was no one on the draft. Designer Chen Jian added these two starlight patterns when he felt the space in the plaster model

② at that time, the review process was not as strict as it is now. The samples have been sent out and sent to overseas dealers to see the samples. Only when the mint found that there was a difference, it had to take the samples first. I didn't expect that overseas dealers thought this effect was particularly good. This starlight is similar to the cross of foreign countries. It means blessing, peace and being with God. As a result, it is very popular in overseas markets< (3) 85 gold cat 1 / 10 ounces, China's first "dynamic" Panda Gold Coin

[features]

(1) designed by Gu Xingbao, a senior gold and silver coin designer<

GU Xingbao is another design master of Shanghai Mint after Chen Jian.

the composition of the 85 Panda Coin adopts different creative techniques. Instead of the previous static picture, the "dynamic" element is added. The "Panda" in the picture is bold, holding on to a small bamboo branch with both hands, and not worrying that it will be broken by its fat body“ "Panda" is timid, its two eyes, staring to the ground, for fear of accidentally falling down, will touch the arm and hurt the leg. The most vivid one is the depiction of two feet. I want to lift them up, but I can't< (4) 86 golden cat 1 / 10 ounces, China's first set of panda coins to win the domestic awards (1986 "China Arts and crafts Hundred Flowers Award" gold cup award)

This is the first time that panda coin has won the award from the domestic arts and crafts instry< (2) for the first time, "Panda" is endowed with three-dimensional and powerful power.

the 1986 version of panda gold coin was made by Yan Jingkui of Shenyang Mint in northern China. Yan Jingkui used the change and combination of lines to reverse the docile and lovely image of Panda.

[features]

(1) China's first panda coin with "plum blossom" design

on the face of the coin, there is a place that looks like a free pen, which is the two ends with the face up, and there are two plum blossom decorative patterns, but it has a rich decorative effect

(2) Yan Jingkui of Northern Shenyang Mint made "Panda Coin" again, adding the design of inner and outer circle

in addition to the main picture of Panda Coin in 1988, there is a mirror outer ring. The outer ring mainly includes weight, fineness, material, denomination and other elements. This kind of composition and setting has changed the vision of the coin surface, and its dignity is closer to the color of "national authoritative currency"

the method of distinguishing the true and false of cat coin

the premise of Panda Coin Collection and investment activities is that you should learn to distinguish the true and false of Panda Coin. If you are a veteran of Panda Coin Collection, you will naturally have the "insight" to recognize the fake. However, new collectors should pay more attention to the authenticity of panda coins. The following are some good methods:

check the front and back patterns: e to the casting equipment, the fineness of counterfeit coins can not be compared with that of real coins. Under the magnifying glass of more than 20 times, there are great differences between real coins and counterfeit coins in the relief of Temple of heaven on the front and panda hair on the back

silk teeth: since 2002, the anti-counterfeiting technology of oblique teeth has been adopted for Panda Gold and silver coins, but since then, the fake panda coins are still straight teeth, which shows that the counterfeiters are beyond their power, and the anti-counterfeiting is effective

size: when the people's Bank of China issues Panda Gold and silver coins every year, it will announce the diameter and size of the gold and silver coins issued in the current period. It can accurately measure the diameter and thickness of the gold and silver coins with vernier calipers, which are used for coin collection and identification, and most of the counterfeit coins can also be identified

weighing: of the ten yuan silver coins for pandas, only those in 1983, 1984 and 1985 weighed 27 grams, and those in 1987 weighed 33.6 grams. In addition, there were commemorative silver coins weighing two ounces in 1991, and the others weighed about 31.1 grams per year. However, the weight of counterfeit panda coins was mostly insufficient

Packaging: the original packaging of panda silver coin also helps to identify the authenticity. For example, gold coins usually have original plastic envelopes, while silver coins usually have original crystal boxes

mirror: the ten yuan face value of the ordinary panda silver coin can be seen under the high-power magnifying glass die-casting trace, so the mirror effect is insufficient. However, most of the panda counterfeit silver coins are silver plated, and the mirror effect is very good. Compared with the refined coins, the mirror effect is better. However, it is also because of the silver plating, even the details of the molding and micro marks are covered up, exposing the hypocrisy<

academic research: the investment of Panda Coin, Panda Coin, undoubtedly, has made an unprecedented contribution to the establishment of China's modern gold and silver coin in the world. In China's modern coin, if we have to jump out of the recognized international coin, then Panda Coin is the right choice. In the past 30 years since 1982, although the glory of panda coin has been dim occasionally, it has continued to contribute its magnificent movements to cat fans all over the world. It's the panda coin that makes the cat fans intoxicated and sweet. It's far more than just a few words

from the perspective of investment and collection, most of the ordinary coins in Panda coins belong to defensive investment varieties, and their prices fluctuate around the international gold and silver prices. Of course, silver coins in ordinary panda coins are more suitable for public investment and collection. Most of the refined panda coins and panda commemorative medallions belong to the category of offensive Investment: they have a small circulation, are exquisitely made, and the premium is not lower than the international gold and silver price, so the characteristics of the collection are more obvious. We might as well roughly classify panda coins as follows, and then graally discuss their investment and collection value: common gold coin, common silver coin, refined small size gold and silver cat, large size gold cat, large size silver cat, plus character cat coin, platinum palladium cat coin, official commemorative medallion

there are several kinds of "plus" panda coins: one is issued in commemoration of the whole five or ten years of panda issuance, including the thickened gold and silver cat in 1991, the one ounce, one quarter ounce and one tenth ounce gold cat in 1996, the platinum and gold plated kilogram silver coin in 2002, the gold and silver set coin for the 25th anniversary of panda issued in 2007 and the gold and silver commemorative coin for the 30th anniversary of panda issued in 2012. This kind of Panda Coin and ordinary Panda Coin are brothers, but their status is more special and eye-catching. Another clock is the panda coin to commemorate an event, such as coin Expo series coin, commercial bank series coin, China tourism year, Chongqing Municipality, Shenyang Horticultural Expo, etc. This kind of coin and ordinary Panda Coin can only be regarded as cousins. They just borrow the model of panda coin to add

in addition, this kind of problem is easy to be blocked by the network, and it will be less issued in the future
What's the purpose of the above BC writing so many flowery words? Does it have practical effect, and is the red envelope so easy to get

9. It should be understood as follows: under the condition of devaluation of the US dollar, the monetary authorities adopting the US dollar pegging mechanism must maintain the inherent exchange rate level by selling US dollars at home and putting in their own currencies. That is to say, through open market business, the local currency will depreciate relative to the US dollar at the same time, which requires the consumption of US dollar reserves. In order to maintain the relative stability of US dollar reserves, As for the phenomenon that "most developing countries can only continue to increase their exports of raw materials", it is probably because most of these countries have inefficient financial markets, unstable political and social environment, and no comparative advantage in instry, commerce and service instries, and nothing can be exchanged for us dollars except raw materials, It's hard to absorb a large amount of US dollars by double surpluses like China's (in fact, China is not very clever either. Apart from exchanging raw materials, other items are mainly primary procts and capital projects. Look, American multinational companies are secretly laughing in the corner). What's more, most of the international settlement currencies of such countries' exports (that is, "raw materials") are also US dollars. Why else do they stare at US dollars. In fact, this has become a strange circle - in order to maintain the stability of the exchange rate, it is necessary to exchange real gold and silver for the US dollar, and what should we do if the US dollar continues to depreciate
for these countries, pegging to the exchange rate will play a certain role in curbing hyperinflation and maintaining economic stability. It is wise to adopt the appropriate mechanism at the right time, and it can not be generalized. Moreover, the depreciation of the US dollar is also relative to the local currency. If the US dollar does not depreciate, or if it is pegged to other single currencies (except a basket of currencies), those countries will not have to sell raw materials or take such risks. Americans are very smart. They will find the best balance between keeping their reputation and continuing to collect Seigniorage and taking advantage of opportunities. As long as the powerful multinational companies and financial institutions, efficient financial markets and stable political and social environment remain unchanged, the money will still flow back. If you pay the bill now, blame yourself for not working well
in those days, the Japanese sold cars for us dollars and went to the United States to buy real estate, but they still failed, helping the old us out of the trap in vain. This time, those who pay the bill are more greedy and stupid. At least, the real assets are mostly capital intensive and technology intensive procts (even if he wants to sell raw materials). What about this time
to add: Although RMB is not strictly pegged to the US dollar now, in fact, it is always concerned about the US dollar exchange rate. Why? In 2008, China's top ten trade deficit countries included Iran, Saudi Arabia, Oman and Angola, and Malaysia and the Philippines, two oil and metal, rubber and procts exporters. There is also Australia. Wool, iron ore and oil and gas, the major items of trade with Australia, seem to be settled in US dollars. The United States is China's second largest trading partner and source of surplus. It is one of the top ten countries with surplus, and Mexico, the oil procer, is the last one to admire. The top three import commodities are: automatic data processing equipment and its components, iron ore and its concentrate, and crude oil. Oil procts and primary shape plastics are the fourth and seventh respectively, and soybean is the fifth. In the top ten, metals and their procts accounted for four, agricultural procts accounted for five, and automobiles were the tail. In the world, except for automobiles, it seems that the settlement currency of these procts is US dollars. " The automatic data processing equipment and its components are also a big part of "automobile" Lao Mei. No dollars? Brother, did you make a mistake
it's still a matter of proportion. My understanding is so simple
