What does virtual currency zero mean

1.

virtual currency is the currency used for electronic circulation. Now the scope of virtual currency is very large, including q-coin, bitcoin and so on. With the development of digital currency, virtual currency is becoming more and more abundant, which may become the mainstream in the future. For example, BTC, EOS, bcbot and so on are not only virtual currencies, but also algorithms, landing projects and technologies

virtual currency is mainly issued by online game service providers to purchase game props, such as equipment, clothing, etc. But at present, the use of virtual currency has gone far beyond this category. Virtual currency can be used to buy game cards, physical objects and download services of some movies and software

extended data:

real risk

as the proct of e-commerce, virtual currency has begun to play an increasingly important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers

fraud

the private transaction of online virtual currency has realized the two-way circulation between virtual currency and RMB to a certain extent. The activity of these traders is to buy all kinds of virtual currencies and procts at a low price, and then sell them at a high price to earn profits. With the increase of such transactions, there are even virtual mints. In addition to the virtual currency provided by the main company, there are also some people who specialize in "virtual coin making" to obtain virtual currency by playing games and then resell it to other players

Taking Wenzhou as an example, there are about seven or eight such "virtual mints" with four or five hundred practitioners. This not only creates a bubble for the price of the virtual currency itself, but also causes trouble for the normal sale of the issuing company. It also provides a platform for selling and collecting money and money laundering for various cyber crimes. p>

impact system

in modern financial system, the issuers of money are generally central banks, which are responsible for the management and supervision of money operation. As the equivalent exchange goods used to replace the real currency circulation on the Internet, the virtual currency on the Internet is essentially the same as the real currency. The difference is that the issuers are no longer central banks, but Internet companies

if the development of virtual currency makes it form a unified market, each company can exchange with each other, or virtual currency is integrated and unified, and all of them are based on the same standard and price, then in a sense, virtual currency is currency, which is likely to form a threat impact on the traditional financial system or economic operation

2. It's the currency used in the virtual world. There is no real object, just a symbol.

3. Domestic trading of virtual currency is not allowed
obviously, you have been cheated

4. First of all, bitcoin is a decentralized monetary system
for example, both RMB and US dollars are issued by banks, but bitcoin is similar to the treasure in a treasure hunt game. Everyone has the opportunity to "issue" bitcoin himself
in fact, the essence of special currency is a lot of special solutions generated by a lot of complex algorithms
the system will choose a correct answer every ten minutes. Whoever can find the correct answer in the first ten minutes will get a reward
the upper limit of bitcoin is 21 million. When bitcoin was born in 2009, each reward was 50 bitcoins
ten minutes after its birth, the first batch of 50 bitcoins were generated, and the total amount of money at this time is 50
then bitcoin grew at a rate of about 50 bitcoins per 10 minutes
when the total amount reaches 10.5 million (50% of 21 million), the reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, or 50% of 1050), the reward will be further halved to 12.5, and so on
therefore, bitcoin circulating in this mode can not be recovered to zero, because everyone is the issuer of bitcoin. Unless everyone clears their account number and no longer digs, bitcoin will always be active.

6. Now there are many child care centers, which provide convenience for many families, save a lot of trouble, and provide professional and considerate care. However, in the market, the quality of the confinement center is good or bad, which needs many families to distinguish by themselves. There are two sides to this. Let's take a look at the precautions of the confinement center today

the following aspects should be paid attention to when choosing a confinement center:

1. Specialty: mother can get good care and protect herself with professional medical knowledge

2. Baby nursing specialty: baby's guidance in breastfeeding, baby's rest, changing diapers, bathing and swimming, umbilical cord nursing, All aspects of jaundice nursing can achieve good nursing, doctors' rounds, nursing, and family members are at ease.

3. Mother's diet conditioning specialty: the diet requires periodic conditioning, low salt and less oil, and balanced meat and vegetables. As long as the nutrition is balanced, no matter how much you eat, you won't get fat. Many mothers feel that they are cows after giving birth to their babies, and their families care about their babies, No one cares about themselves. In fact, the mother's care is the most important thing. A mother needs a professional diet. When a mother is in a good mood, what she eats is good, and the milk will be good, the baby will naturally not have to worry. All the milk problems are actually the mother's own problems, as well as the influence of family, and the anxiety of mood

4 My mother's postpartum body repair major: not only from the body shape and posture, but also from the organ reset, we need the guidance of professional physiotherapists, in order to slowly build confidence, with the salt less oil diet ideal, not thin is difficult, I met a lot of mothers in the confinement center to do the confinement can thin more than ten jin, it must be a good confinement center

5 Finally, the environment: whether the environment is located in downtown area, automobile exhaust pollution, chemical pollution, whether the transportation is convenient, whether the driving or subway bus is convenient, whether the room windows are soundproof, whether there are garbage mps, viacts, green areas, parks, whether the environment is beautiful, whether there are rivers and streams, and whether the temperature and humidity are appropriate, Is it a single family or a single story Hotel, or a community renovation

7. In this way, I will explain to you that the IP on eth0 is automatically obtained, and the IP on eth1 is manually set (also required by VPC)

configuration process:

1. Open the / etc / network / interfaces file of Ubuntu. The default content is as follows:

auto Lo
Iface Lo INET loopback

2. Eth0 is to obtain IP automatically, so it does not need to be configured. Insert the IP information of eth1 to set IP manually. After editing, the content is as follows: Auto eth1, Let the network card mount automatically after power on.

auto Lo
Iface Lo INET loopback
auto eth1
Iface eth1 INET static
address 192.168.0.101
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.2


3, Then open the terminal and run the following command to restart the network card:

$/ etc / init.d/networking restart

you can also restart the network card to make the new configuration take effect. The advantage is that it does not affect other network interfaces:

$sudo ifdown eth0

$sudo ifup eth04, It can be changed to:
auto eth0
Iface eth0 INET DHCP

you can also directly enter the following command to get the address
sudo dhclient eth0

5. Configure the address of DNS server, You can use up to three DNS servers

$sudo VI / etc / resolv. Conf

nameserver 202.96.134.133
nameserver 202.96.128.68
nameserver 202.96.128.166

for & quot; resolv.conf" The amendment is effective immediately. You can use the NSLOOKUP command to query the DNS server to verify & quot; resolv.conf" Configuration file

how to view DNS

$less / etc / resolv.conf
