Address with BTC more than three digits

1. Hello, according to the situation you described, the account holder cannot be traced. Otherwise it won't be cryptocurrency. This anonymity is the characteristic of electronic cryptocurrency

although many platforms also have identity authentication (after authentication, the amount is larger, which seems to cooperate with the law to prevent money laundering)
however, the phenomenon of non authentication (or fake authentication) is also common
instant authentication. As an ordinary user, it is impossible to check who the account holder of other platforms is.

2. Let's make a brief conclusion: according to the data a year ago, about 500000 BTCs are worth a little bit of taste:
1) two American brothers, Cameron Winklevoss and Tyler Winklevoss, claim to hold about 1% of bitcoin in the world? Now the total amount of bitcoin in the world is about 12 million BTC, that is to say, these two brothers hold about 120000 bitcoins. Maybe you don't think these are too valuable, but note that the starting price of bitcoin for these two people is below $10 / BTC. At the current market price of $430 / BTC, the yield is...... (2) Li Xiaolai claims that he is the first person in China to hold bitcoin, holding six digit bitcoin (no video link found.)
3) after the founder of the silk road was arrested, his 140000 bitcoin was seized by the FBI [2]
therefore, the people who have the most bitcoin should hold more than 1% of the world's total. This can be seen from the daily BTC holdings list
more systematic research comes from academia. The Israeli mathematician ADI Shamir (if the name is unfamiliar, he is the s in RSA algorithm) published a paper "quantitative analysis of the full bitcoin
transaction graph" in 2012, which analyzed the transaction records of the first 18000 blocks in the special currency system (as of May 13, 2012), This paper studies some interesting problems in bitcoin market
in their analysis results, at the end of the first 18000 blocks of chain, the entities with the most bitcoin holdings range from 200000 to 400000 BTC (the article does not give specific figures), and only one entity with more than 200000 bitcoin holdings. In history, the largest amount of money held was more than 500000 BTC, with two entities
note that "entity" is used instead of "person". In the analysis method of this paper, bitcoin wallets that may belong to the same owner are classified as the same entity. This entity may not only be a person, but also be a trading organization such as Mt. GOx
in addition, by analyzing the table of the most active entities given in the article, the income of the people with the most income (excluding expenses) is below 700000 BTC. In other words, the person who owns the most bitcoin will not hold more than 700000 BTC

3. Number of what, you can use the length of direct judgment, keywords can be compared with regular. Bitcoin verification should have a formula. You can find the formula, put the string in for calculation, and see if it conforms to the rules

4. Of course, this is more than three digits, and it's more than three digits. As long as you have a good collection, you can even surpass the current value

5. CVV2 code will be locked if it is wrongly input three times in a row on the same day, and will be automatically unlocked after the end of the day.

6. Solution: if the number is no more than 500, you can only choose P2 (1) from 2 and 3, and the other two can choose 2 P4 (2) from 4 digits other than the selected number. P2 (1) xp4 (2) 2x4x3 = 24

7. IP address is 4 segments, each segment is composed of any number between 0 and 255, and then a segment can be determined according to the country and region!

8. No more than means equal to or less than, so no more than three digits are one digit, two digit, three digit.

9. The values of hundreds are 0, 1 and 2. When 0 is taken, there are 10 kinds of the following two digits, and there are 100 kinds. When 1 is taken, there are 10 kinds of the following two digits, and there are 100 kinds. When 2 is taken, the second digit can only take 0 ~ 5, and there are six kinds of methods. When the second digit is 0 ~ 4, there are 10 kinds of methods for the third digit. When the second digit is 5, there are 6 kinds of methods for the third digit, So there should be 256 ways to take a group of three digits, while there should be 256 ways to take four groups of digits × two hundred and fifty-six × two hundred and fifty-six × 256 methods

10. Let the original three digit's hundred, ten, and indivial bits be a, B, and C respectively,
then the sum of the three digits obtained by exchanging the hundred and indivial bits and the original three digits is
(100a + 10B + C) + (100C + 10B + a) = 100 (a + C) + 20b + (a + C),
to make each digit even, you must:
1, a + C has no carry (the thousand digits after carry are 1)
2 B ≤ 4 (if B ultrasound exceeds 4, 20b has carry)
3, a + C must be even
so when a = 1, C takes 1, 3, 5, 7, 5 * 4 = 20

when a = 2, C takes 2, 4, 6, 5 * 3 = 15
when a = 3, C is 1, 3, 5, 5 * 3 = 15
when a = 4, C is 2,4, 5 * 2 = 10
when a = 5, C is 1,3, 5 * 2 = 10
when a = 6, C = 2, 5 * 1 = 5
when a = 7, C is 1, 5 * 1 = 5,
therefore, there are 20 + 15 + 15 + 10 + 10 + 5 + 5 = 80.
