What virtual currency is rare

1. If virtual money wants to be related to real money, it needs a bond, an organization or a group to identify with, and establish a rule, then it has value. Without everyone's approval, circulation has no meaning

2. Among the commemorative coins issued in China, the one with the least circulation is the commemorative coin for the 30th anniversary of the founding of Ningxia Hui Autonomous Region, with a circulation of 1.56 million; The second is the 40th anniversary coin of the people's Bank of China, with a circulation of 2.06 million; The circulation of commemorative coins commemorating the 20th anniversary of the founding of the Tibet Autonomous Region is also small, 2.61 million, so the prices of these commemorative coins are relatively high.

3. At present, bitcoin is the only one that is popular, and the others can't be operated and traded. In addition, bitcoin's entry cost is relatively high, so it is not recommended to buy or sell bitcoin. Or do the real economy honestly

4. The security of tix is relatively good. I have bought a virtual currency for a long time, and I have never lost money. Moreover, the income has increased steadily.

5. Words + semantics + Grammar 60 points, basic condition at least 19 points
reading and solving 60 points, basic condition at least 19 points
listening 60 points, basic condition at least 19 points

specific to each question
words + semantics + Grammar:
1-15 questions: score = number of right questions x 10 / 15
16-27 questions: score = number of right questions x 15 / 12
28-54 questions: score = number of right questions X 35 / 27
reading part:
55-75 question: score = number of right answers x 60 / 21
listening part:
question 1: score = number of right answers x 9 / 5
question 2: score = number of right answers x 12 / 6
question 3: score = number of right answers x 12 / 5
question 4: score = number of right answers x 17 / 12
question 5: one time, Two times, three times for each question (question 1, question 2) two points for each question

if the total score is over 90, you can pass it. However, you must score at least 19 points for each single item. I suggest that you practice listening and reading more. You can listen before you enter the examination room and keep your feeling. You should also pay attention to the timing of reading

6. First of all, the formal virtual currency is to speculate, similar to the stock speculation, but generally there is no limit, so whether you earn or not depends entirely on your ability
in addition, it is investment. There is no investment theory. Only the assets that will increase in value are worth investing. Firstly, whether virtual currency is an asset is still a problem. Secondly, most of the investments that rely on friends to pull are scams

7. The quantity of virtual currency can be changed, as long as a number is changed in this agreement, which is very simple. In fact, the quantity of virtual currency has no real value. There are only 21 million bitcoins, 28 million Ruitai coins, 84 million Wright coins and more dog coins, but their total market value is not a fraction of bitcoin.

8. Fortress 1 doesn't say much, but when the owner looks at the picture,
he despises those who don't know how to a large section at will http://www.114bt.com/btimg/2006/12/6/6929252.jpg

9. One at most! You want to add a vertical force (not a horizontal force), and the friction force is opposite to the direction of motion! The direction of motion is the same as the direction of the force you are applying!
