Total market value of digital currency
Publish: 2021-04-16 13:09:31
1. In 2017, the total market value of global digital currencies once exceeded US $600 billion, with an annual maximum increase of 3497.98%. The types of digital currencies increased to 1334, achieving explosive growth in terms of both the total market value and the number of currencies. According to the development route of global digital currency, digital currency can be divided into: 1. Currency type represented by "bitcoin"; 2. Decentralized application development "platform" type represented by "Ethereum"; 3. Various decentralized "application" types
2.
If you use three words to describe the latest bitcoin, it can only be three words & quot; It's going crazy;. On February 19, the price of bitcoin reached a high of US $56000, with a total market value of US $1 trillion{ RRRRR}
coupled with the global popularity and high liquidity of bitcoin, long-term holders believe that bitcoin is an ideal medium for long-term wealth storage and will appreciate over time
how does bitcoin work? In the bitcoin system, the way money drives is not the digital transfer of cash that most people imagine. When Alice remits money to Bob, Alice's process is like recording on the account book that everyone sees that she transferred $1 to Bob. If Carol wants to charge Bob a dollar, she can see from the same ledger that Bob does have a dollar
3. For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency
virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency
in 2013, the central bank, together with five ministries and commissions, issued the notice on preventing the risk of bitcoin, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, not in the form of currency and legal currency< At the same time, digital currency is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.

4. Bitcoin, of course, is the hottest one. In addition to bitcoin, there are also:
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin
based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior
6. Novacoin
another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities
the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward
7, infinitech
published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.

5. The market value of digital currency is equivalent to the market value of stocks in circulation, which is calculated by multiplying the market price of digital currency by the quantity in circulation. The formula is: market value = current price of digital currency * quantity in circulation
generally speaking, the market value is determined by the quantity in circulation rather than the total circulation. Because circulation quantity can better measure market value. The locked and predetermined ones can not be sold on the open market, which will not affect the currency price, so it will not affect the market value. The method of using circulating quantity is similar to using circulating shares to determine the market value of traditional investment
at present, the market value of bitcoin has reached more than 70%, occupying an absolute dominant position, while the market value of other currencies is declining. In the long run, the market value of the whole digital currency is growing. If we can seize the opportunity, we will get rich returns.

7. What does it mean to set the entered market value of currency? Just like a stock, digital currency can be traded in the whole network exchange in the form of stock
8. 1、 What is intranet
generally speaking, it is a local area network. Internet cafes, campus networks and office networks all belong to this category. In addition, fiber to the building, community broadband, ecation network, cable modem Internet, although the geographical scope is relatively large, but in essence, it is still based on Ethernet technology, so it still belongs to the intranet< How to judge whether I am an intranet or not
you can ask your ISP to see if you are one of the above users. If you dial up every time you surf the Internet, you are not an intranet user. But the situation is not absolute! A more reliable method is to judge by IP address
open the command prompt window (start → run Win9x, enter command.com Win2K, XP, enter cmd.exe), and enter ipconfig at the DOS prompt
the IP address of the machine is displayed in the IP address item
when the IP address is one of the following three forms, you are in the intranet:
10.0.0-10.255.255
172.16.0.0-172.31.255.255
192.168.0.0-192.168.255.255
if you have multiple network connections, as long as one IP does not match one of the above three forms, then you are not in the intranet
Third, I am an intranet, how to improve the speed of BT download
first of all, it is recommended that you upgrade your system to XP. This is because the total bandwidth of the intranet is limited. When the bandwidth is tight, users using Win2K and XP have an advantage over users using Win9x. Secondly, most of BT software consumes system resources. Under Win9x, it is very easy to cause the system to slow down, lose response and even blue screen, while XP based on NT kernel is much better than Win9x in resource management and stability
client software I strongly recommend BitComet
BitComet is a P2P free software based on BitTorrent protocol; Efficient network kernel, multi task download at the same time, still keep little CPU memory occupation; It supports selective downloading of files in a torrent; Disk cache technology can effectively rece the damage of high-speed random read and write to the hard disk; Only one monitoring port is needed to meet all download needs; Automatically save the download status, no need to scan the file again, no need to scan the file for seed; Support multi tracker protocol; Green software, do not need to install, only run-time Association. Torrent file; Multi language interface. Its original name was simplebt. It also supports UPnP automatic port mapping, automatic opening of windows network sharing and firewall port
Run BitComet after installation to open the options dialog box. In the advanced settings item, make sure to select "support tracker's intranet report extension", in the network connection item, select all the options, and in the disk cache item, increase the cache value according to your memory (so as to avoid premature warping of your hard disk)< 4. I've done what I said before. Why not I can't upgrade to XP for some reason)
then you need to do port mapping. If you surf the Internet through proxy server, you can use portmap to do port mapping on the server. Please click here to download portmap
if you use a router, the setting method of each router may be different. So please read the router manual or consult the dealer
this operation enables all kinds of services on LAN to be accessed by Internet
software mapping
winrote Pro is a proxy server software that integrates router, DHCP server, DNS server, NAT and firewall. At the same time, it is also a mail server software that can be applied in LAN. Therefore, it can not only realize that all microcomputers in LAN share an Internet connection (connection mode includes modem, ISDN, xDSL, DDN It can also realize the mail management in LAN and the mail exchange between LAN and Internet
winroute software is very simple to install and use. It only needs to be installed on the server. It is an excellent proxy server software for LAN sharing Internet connection. It can realize reverse proxy function by port mapping, and let the external access some services provided by the internal network protected by Nat
porttunnel means "port channel" in Chinese. Its function is to specify a channel on the server for the client's computer, so that the client can directly establish a connection with the Internet. It must run on the server side to achieve the purpose of port mapping<
port mapping of ADSL
some adsls have built-in proxy function, which enables us to realize multi machine sharing and Internet access without the need of host computer, but it is impossible to access web, FTP and other services from outside network. Next, we use omni-directional ADSL 1680 to realize the service of accessing intranet web service from outside network
access IP address: 10.0.0.2 (this is the default intranet IP address of 1680), the default user name is "admin", and the default password is "qxcommsupport"
click "virtual service" to enter the main interface of port mapping configuration
fill in the "public network port" with the port 80 that we want to open on the Internet, and fill in the "Intranet port" with the port 80 that has been opened on the intranet machine
select whether "port type" is TCP protocol or UDP protocol (for example, TCP is used for web and FTP protocol, and UDP is used for QQ protocol)
finally, add the IP address of the intranet open web service to the "host IP"
broadband router port mapping
Enter "192.168.0.1" (assuming that the IP is a router) in the IE address bar to log in to the router
enter the initial password
click "virtual server / DMZ" to enter the configuration main interface of port mapping
if you want to add a web server, check "HTTP (port 80)" and fill in the last digit of the IP address of the intranet host, enter the port number 80 in "(Port No.)" and click the "save" button below to add a port successfully
in fact, the use of winroute, porttunnel, ADSL and broadband router is very simple. We only need to add different IP addresses and ports to realize various services. Making good use of the mapping function of software and hardware will bring infinite convenience to our application on the network

9. It is MLM + illegal fund-raising, illegal and criminal, you can refer to V treasure money, Ponzi fraud and other information. According to his introction, each Mint is 800 yuan, and 5.2 yuan can be withdrawn every day. The maximum yield is 200 days before 1040 yuan (including 800 yuan of principal and 240 yuan of profit) can be obtained. There are still five days of profit to pay the handling charge. It's going to take a hundred more. 800 yuan takes 800 / 5.2 + 5 days, about 160 days. That's more than five months. If he can pull one line in these months, he will be able to maintain his expenses, and multiple lines will be a big profit. The person at the top of the pyramid can make huge profits. Only he knows when the capital chain will break. All the money paid for the mint is equivalent to the membership fee of MLM. There is a leader award for pulling the head. The relationship between the upper and lower line is very obvious. One day, if he thinks that he can achieve a certain goal, he will escape, or change his name to continue to develop. Or the capital chain breaks and runs away. Just because 800 yuan membership fee is not much for many people, many people start to invest in the trial, there is really a dividend, so they believe it. In addition to his brainwashing propaganda, the concept of stealing pleasure is compared to bitcoin and other virtual currencies, which makes people feel very complicated and mysterious. They can't figure out the essence. In fact, apart from the name of bitcoin, it doesn't have any characteristics of bitcoin. Please don't believe that if you go in, don't continue to advertise for him, because what you do is fraud, is illegal and criminal, and will harm your relatives and friends to do it with you. Please remember there's no pie in the sky.
