The use of virtual currency
{rrrrrrr}
bitcoin (BTC) is a digital currency with a total amount of 21 million. It has the characteristics of decentralization, globalization and anonymity, just like the Internet. It means that transferring bitcoin to the other end of the earth is as simple as sending e-mail, low-cost and unlimited. Bitcoin is also used in cross-border trade, payment, remittance and other fields
the liquidity and limitation of bitcoin determine that bitcoin can act as a monetary function equivalent to general equivalent, or as a measure of money, but this measure is not a physical measure like gold, but a digital proct
related concepts:
1. Address
the address of bitcoin world looks like this. The address itself is just a string of codes, just like your bank account number 321 million 3288372, which is used to mark an account. Everyone can have countless addresses. The address is public
2. The bank records how much money there is in the bank account
the amount of money in the bitcoin address is recorded by the whole bitcoin network. Each complete bitcoin data will record how many bitcoins are stored in this address
each node participating in the bitcoin network can save a complete of bitcoin data, and everyone has a backup on hand to prevent counterfeiting
3. The key (private key)
the key is another string of characters you only know. The key is used to operate the money in the bitcoin address. Key and address are the relationship between a key and a lock. Each address has only one password, and each password also operates a bitcoin address
with the key, you can control the money in the bitcoin address and pay to anyone. The key should be absolutely safe. The lost or deleted key can never be found, and the money in the corresponding bitcoin address can never be used
the key needs to be kept absolutely secret. Anyone who knows the key can steal all your bitcoin
4. Wallet
the transaction process of bitcoin will involve a lot of complex calculations. In order to simplify the operation, we have made wallets. The wallet has client software on the computer, and also has an online web version. The function of the wallet is to pay with a little touch, and the complicated calculation behind it is left to the wallet to complete
5. Security
if you use the computer client software, you can recommend multibit or bitcoin QT. Both are official software recommendations for the bitcoin community. The installation of these two softwares must be downloaded directly from the official website, and the check code must be checked before and after downloading. This is to prevent someone from tampering with wallet software and stealing keys
6. Mining
about every 10 minutes, some new bitcoin will appear in the bitcoin network, which can be imagined as throwing money in the sky. Whose pocket these scattered money fall into mainly depends on whose computer calculates fast. The faster you calculate, the more likely you are to find the money. Mining is to use the computer to calculate, to pick up the money< br />
the main function of bitcoin is speculation, payment and asset category

vitality coin is the reward coin of sports proof mechanism of happy running circle.
In 2008, a pseudonym software developer proposed bitcoin as an electronic payment system based on mathematical proof. The idea is to create a means of exchange independent of any central authority that can be transferred electronically in a secure, verifiable and unchangeable manner
bitcoin is a kind of P2P virtual digital currency based on blockchain technology, which can be traded with the world
bitcoin can be used for many purposes, including providing funds for companies, investing in cash and transferring money free of charge. Bitcoin is usually associated with criminal activities such as drug trading, cyber crime and money laundering, because it is almost impossible to associate bitcoin wallet with anyone
it's not a reality. Up to now, I still think it's stupid to make money by buying and selling domain names. I know it happens sometimes. It's like a high-risk, low return investment
as a result, the Internet did. Now, 20 years on, domain names are cheap, and search engines make them brand specific Note: the author means that the convenience of search engines makes domain names cheaper and cheaper. Domain names are only related to brands.)
What does this have to do with the value of bitcoin
this is an example of how people's views on value change with the development of technology
at this point, most people see bitcoin as money. The chairman of the US SEC said, "yes, that's how drug gangs use it. Everyone I know thinks so.". It's called "bit coin" for a reason
bitcoin maximalists call it hard currency, critics call it fake money, and veteran players call it cyber currency

The role of digital currency:
1. First of all, the central bank's digital currency can provide a huge data base for monetary policy and macro Prudential policy, so that the regulatory authorities can collect real-time trading books of different frequency and different institutions according to their needs, and it is complete and real. This information advantage can help the central bank use policy tools more accurately and flexibly
Secondly, the central bank's digital currency technology can track the flow of funds and help the regulatory authorities to comprehensively monitor and assess financial risks. Finally, the central bank's digital money technology is concive to the transmission of interest rate of monetary policy. Digital currency technology supports "point-to-point" payment and settlement, which can improve the liquidity of market participants. Only the digital currency of the central bank, which is generally accepted by the whole society, can radiate this advantage to the participants of different financial markets, so as to improve the liquidity of financial markets. This will make the term structure of interest rate smoother and the transmission mechanism of interest rate smoother
extended data:
digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: because it comes from some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation.
the value of virtual currency is that it is based on blockchain technology, has high security, and is suitable for being a decentralized currency after a period of depression, the price of bitcoin has recovered again recently, standing at the price of US $40000, which is the biggest rebound in the price of bitcoin since this month. In fact, since last year, the bitcoin market has ushered in a wave of rising prices. Some analysts say that the main driving force for the rise is that large financial institutions begin to enter the market and take bitcoin as a part of their asset allocation. Some well-known investment companies and fund companies, and even conservative insurance companies regard bitcoin as one of the investment options
diamond and rust jonbaya
My God! Your phantom appears again
but it's not unusual
just because of the full moon tonight, you happen to call
I'm sitting here on my mobile phone
listening to my familiar voice, it was a few light years ago
as if falling down continuously
vaguely remember that your eyes are bluer than robin's eggs (note)
you said that my poem is terrible
& quot; Where are you calling from& quot;< br />" At a phone booth in the Midwest
ten years ago, I bought cuff links for you, and you also gave me some things.
we all know what memories can bring us.
they give us diamonds and rust.
when you suddenly appear in front of me, you are already a legend.
a phenomenon that can't be guarded against.
a real tramp, you drift into my arms,
and your stay, Like a short voyage on the sea
with the blessing of the virgin
to protect you from being hurt
now, I see you standing in the yellow leaves
your hair covered with snow
you smile,
in front of the window of the hotel overlooking Washington Square
you and I exhale like white clouds
condensing in the cold air
for me
we almost died at that time
now you say to me, You are not nostalgic
so please find another word to replace
you have always been good at playing with words
to make it ambiguous and difficult to understand
because now I just need such ambiguity
everything in the past is too clear
Yes, I love you deeply
if you give me diamonds and rust again
I will tell you that I have paid a price, When they come into contact with old Western songs, there are several pieces that they can't do. On the one hand, they can practice their playing skills. On the other hand, they have beautiful melodies that last for a long time< After Joan Baez, an American folk song, there are several such works handed down from generation to generation, such as "Donna, Donna", "the night they drop Old Dixie Down" and "diamonds and rust". Among them, "diamonds and rust" is a more difficult piece
Joan Baya has a clear, pure voice and mature skills. Many famous composers are willing to provide her with works to sing, so most of her well-known songs are not written by herself. "Diamonds and trust." is the most well-known one of her own songs
the lyrics of this song are lengthy and the images are complex, so many people can't understand the meaning even after looking up the new words in English. The reason is that the lyrics are about a personal relationship with Joan Baya< In the 1960s, she met Bob Dylan, later known as "the father of folk rock" and the most famous work was "blowing in the wind". They both cherished each other and appreciated each other's talents, so they had a secret love affair
the relationship ended in nothing. In 1975, Joan Baya wrote this song, which is based on the feelings of her teacher and friend. Later, "diamond and rust" is also considered to be her best composition
in English, "diamond" is often compared to "good things in memory". There is a song called "some days are diamonds, some days are stones." its metaphor is similar, while "rust" and "stone" are used to refer to "bad things in memory".
