Is virtual currency useful

1. The function of virtual currency depends on its application scenario planning
the main function of bitcoin is speculation, payment and asset category
Ruitai is an asset voucher and an attempt to digitize assets
vitality coin is the reward coin of sports proof mechanism of happy running circle.

2. At present, WeChat and Alipay are called electronic payment, which are not digital money, and can not completely replace cash
there are also virtual currencies, such as Q currency. These are virtual currencies, purchased directly in cash
in short, digital currency is an electronic currency that can replace currency. At present, digital currency is not regulated, there is no endorsement of national credit, and it is not issued by central banks or authorities, but it is used by members in specific virtual communities, such as bitcoin.

3.

Digital currency is a general term used to describe all forms of electronic currency, whether it is virtual currency or cryptocurrency. It is a form of data expression of value. Through data transaction, it plays the functions of transaction medium, accounting unit and value storage, but it is not the legal currency of any country or region

the concept of digital currency was first put forward in 1983. They only exist in digital or electronic form. Different from the actual paper money or coins, they are invisible. They can only be owned and used on the Internet through e-wallet or designated network. The advantage of digital currency is that there is no bank, the transaction is instant, and the transaction cost is very low. So: coin, token and virtual currency belong to digital currency

the main characteristics of digital currency

1. In terms of payment and settlement, it does not rely on institutions. It is a publicly accessible digital general ledger maintained by the whole distributed network, which is called "blockchain"

2. In terms of issuance and proction, the essence is to keep accounts on a mutually verified public accounting system. Under a certain algorithm mode, find out a string of random codes that meet the conditions, and then package this string of codes with other transaction information into a block and record them in this account book, so as to obtain a certain amount of digital currency

(3) it has no national boundaries, which makes it flow around the world. Virtual world corresponds to the real world, through the exchange relationship between digital currency and traditional currency, under certain conditions, specific digital currency can buy physical goods, and traditional currency can also buy specific virtual goods

In theory, its distributed general ledger system can prevent any participant from forging digital currency and rece transaction risk

The lower transaction cost of digital currency will promote banks and other financial institutions to improve service level and rece transaction costs

Digital currency and mobile financial business model can promote the development of Inclusive Finance

4. If the virtual currency platform runs away, most of your money will be wasted. The possibility of finding it back is extremely low, because the legislation in this area is not perfect, and the police have no legal basis to prosecute those people. In the future, we should pay attention to the security and investment of virtual currency. Once there is a problem, there will be no return and heavy losses.

5. Bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
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.

6. If it can only be traded on a single trading platform, or if there is no trading platform, the opening of Shanzhai coin can be postponed, because the opening time can be decided by the platform itself. However, bitcoin, Ruitai coin, Laite coin and Weimeng coin, which have been open for a long time, generally do not delay the opening.

8. Have a look back
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".

9. In fact, it can be done. Building owners can pay with
virtual currency on the Internet. Many e-businesses support virtual currency payment, which may be a big trend in the future.
