Market value of virtual currency
what is digital currency
digital currency can be used to describe all electronic currencies, including virtual currency and cryptocurrency. Digital currency is a kind of electronic currency without any physical form. Because of its functions and inherent attributes, it is the same as the standard illegal fixed currency, and can also be referred to as the network version of cash. Digital currency is invisible. People need to use and hold it through devices that can be connected to a specific network
T1: eth (the first public chain at present, the underlying platform of Shanzhai coin breeding, and in the speculation of eth2.0) EOS (community consensus + DAPP possible explosion + defi can also join + drop out of high cost performance) Zec (anonymous leader)
T2: Yas (UBI concept, low market value, great potential) atom (cosmos, advantage new public chain), XRP (the decline in 2019 has not risen, so the upward space is still very large) Polkadot dot (Boca, the goal is to surpass Ethereum) KSM (Boca pioneer)
T3: Ada (potential) NEO (myth of 1000 times of the last bull market), ont (strong village), Iost (Iost is currently undervalued, DAPP is also in good development)
there are platform coins in the coin circle, corresponding to HT, BNB, MX
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
How many cryptocurrencies are there in the world
at present, there are more than 1350 encrypted virtual currencies in circulation in the world. So far, according to the total valuation given by the market price, there are 23 virtual currencies with a valuation of more than US $1 billion, 97 with a value of more than US $100 million, and 573 with a market value of more than US $1 million. All in all, the total market value of virtual currency has exceeded US $5 trillion, of which bitcoin, the earliest invention, accounts for more than half. Players generally admit that bitcoin is not the most effective cryptocurrency, nor is it the most covert and anonymous. However, bitcoin is the first one to appear, so it is the most well-known and popular one
so the question is, does the world need more than 1350 cryptocurrencies
even the players of virtual currency will doubt this. No matter how strange the world is, there cannot be so many virtual currencies. In fact, there are so many new ICO virtual currencies emerging in recent years, which complement the "Crazy" performance of bitcoin in this year. Most of these 1300 kinds of virtual currencies can't be recognized by everyone. From the beginning of ICO, there will be many loopholes that no one will fill. When there is a major adjustment in the virtual currency market, many of them will disappear automatically, which means that no one will go to mine any more
this also leads to a problem. When some of the cryptocurrencies have problems, the entire instry chain and market of virtual currency may be involved like dominoes. Even the strongest bitcoin now will also be involved, because the cryptocurrency, in the final analysis, is supported by the "belief" of players
why is bitcoin worth more than other cryptocurrencies
at the time of writing this article, the total value of bitcoin is about US $270 billion, the total value of cash of bitcoin is about US $31.7 billion, and the market value of bitcoin gold is US $5.17 billion. Since bitcoin cash and bitcoin gold are separated from bitcoin, in a broad sense, they should be counted as a part of the total value of bitcoin (of course, you can't refute me technically, just for a rough explanation). Once we add up all the branches of bitcoin, we can calculate the market value of more than $310 billion. As a result, bitcoin accounts for about 60% of all cryptocurrencies in the market
as I have repeatedly said in recent days, bitcoin is not the most effective cryptocurrency, the most advanced, the most anonymous, or even the most stable cryptocurrency. So why is bitcoin so valuable compared with other virtual currencies
it's very simple, because bitcoin has a catalytic factor, that is, the Chicago Board of trade, as well as the commodity exchange, began to trade futures as a "commodity". Then, you will naturally think that since it has been recognized by the futures exchange, will it be further recognized by the US government in the next step. Other virtual currencies are still struggling
however, we have always stressed that since the day bitcoin was traded as a "commodity", its real monetary role, like gold, has been very weak in reality, but as one of the procts of gambling. This means that we all do bitcoin as a speculative activity, rather than a real use
judging from the current situation, bitcoin is no longer the only virtual currency that soars as soon as there is news of "official support". It is like iota, a virtual currency that focuses on the principle of the Internet of things. The news of cooperation with Microsoft came in the last two weeks, and it immediately rose to more than $300. Later, Microsoft came out and said that there was no such thing, and iota immediately fell back. It can be seen that in the future, as long as the virtual currency is recognized by some big company or organization, it will soar like bitcoin
If you really don't know about bitcoin, you will know that the earliest holder of bitcoin has made money. Do you think that bitcoin is rising and he has to sell when he makes money? Will he keep holding it? Are ordinary people, in the face of such a big temptation, can not hold on
later, people were cut like leeks, wave after wave. At least among the people I know and the stories I heard, no one made money because of bitcoin
summary:
what is bitcoin? I don't know. It's like virtual currency. It can't be used for payment or transfer. There's also a so-called dark net
the rise and fall is just like gambling. At the beginning, gold and silver were bought in the same way. Gambling is risky and investment should be cautious. people want to eat all the time when they get the sweets. Do you know what is to stop when it's good? Don't be greedy, you are just a leek in the eyes of bitcoin, not a bundle, understand
at present, bitcoin has the largest market value and the highest acceptance. Bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system
however, there are also many people carrying out pyramid schemes under the guise of bitcoin, such as the spark entertainment bitcoin and Porter coin scam that broke out in bitcoin house before.
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
intranet is the opposite of public network
