2. First of all, I want to explain the principle of virtual currency. Take bitcoin as an example. It is a cryptography currency. Its principle is to give the solution of the irreversible algorithm. After the operation of the irreversible algorithm, the original value of the solution can be obtained, which is a bitcoin. Because of the irreversibility of the algorithm, you can't dece the original value from the solution, so all you can do is try one by one with different values, which is called "mining"
here is an example of "XX coin" algorithm: the original value is a three digit number: ABC, and the password is obtained after encryption algorithm. The first digit is (a + 15) ^ (B + 2) / C, and then the first digit after the decimal point; the second digit is C to the power of (B + 1) + 5.25 * a, and then the first digit after the decimal point; the third digit is (c + 25) multiplied by (B + 43) and divided by the power of a, and then the first digit after the decimal point. Thus, the encrypted data XYZ is obtained. The problem is, even if you know XYZ and the algorithm of the password, you still can't find the original value ABC from XYZ. The only way is to take all kinds of data one by one until there is a solution XYZ (assuming that each ABC in our algorithm can only find a unique XYZ). Well, since XYZ is a three digit number with a range of 0-999, there are 1000 possibilities. We select 10 of them, such as 990-999, as the effective value of "XX currency" to verify. The original value of ABC of these 10 solutions is "XX currency"
since there are only 10 numbers from 990 to 999, there are only 10 original values that can be calculated, that is to say, there are only 10 XX coins in total, and no one can change one. This ensures that the total amount of XX currency is constant and there will be no "inflation". It is the mathematical law that ensures that the total amount remains unchanged. No one can change it, just like no one can change the 11th integer between 1 and 10. To prove his ownership of a XX coin, a digger needs to publish the value calculated by the algorithm, such as 996, to confirm his ownership of the XX coin without disclosing its true value
therefore, the first thing to judge whether a virtual currency is reliable is whether it publishes the algorithm or the source code. Because the algorithm is the fundamental premise to ensure the total amount unchanged and the ownership of the holder
secondly, the currency must be freely tradable. Free trade means to trade with anyone at any time and in any amount. The reason is even simpler. If the state suddenly stipulates that you can only go to the designated store to buy RMB once a month, and each time you can't spend more than 5% of the total amount of RMB you hold, then don't you jump up to revolt< Third, the currency must have a third-party trading platform. As we all know, virtual currency itself is of little value. It is only when you are willing to spend that money on it that it has value. Having a third-party trading platform at least means that everyone agrees with it. Just think, if your unit tells you, after salary does not send RMB, change hair white note, all people must take white note to unit accountant that, according to the exchange rate that day unit formulates change. Do you think your unit is thriving?

3. Hospitals do not have the right to report HIV positive, hospitals can only report suspected positive, only CDC can report. Hospital is in the immune department to do HIV antibody testing, not more than 100 yuan, generally about 80.
4. I don't know about you, but here we are "anonymous charge, real name no charge"!
5. Centers for Disease Control and prevention around the detection of AIDS is free, you can directly carry your ID card.
6. Disease analysis:
Hello! For syphilis examination is not free, in the general hospital can also check, regular hospital examination is safe, for the real name system is the best. It doesn't make a big difference
Guidance:
if you need to exclude it, you can go to the dermatology and Venereology Department of the regular hospital for examination.

7. Some are like boats, some are like fans, and some are like small palms... Looking at the scene in front of me, I can't help but think of a poem: "fallen leaves are not merciless things, they are more protective than spring mud." Is there no emotion? After it turns into soil, it will always guard the flowers and plants. Thinking of this, I have a feeling of admiration for the fallen leaves in my heart.
8. The evolution history of financial and monetary system

9. CDC can be free of charge for class A infectious diseases or infectious diseases prevailing in a large area at that time, and definitely charge for rash and virus examination
10. It's free. You can go as long as you work.
