Bitcoin is a virtual digital currency

1.

1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin

However, some digital currencies have independent issuers

The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Bitcoin is a digital currency

digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold

today's digital currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency

illegal digital currency

in recent years, "virtual currency" represented by bitcoin, Ethernet currency and Leyte currency has been traded centrally on some Internet platforms. With the help of financial technology, the price of these "currencies" has graally spread to investment, financing and other financial fields, which has aroused wide attention from all walks of life

not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence

therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing

2. Hello, bitcoin is a virtual electronic currency. Founder: Nakamoto, it does not rely on specific currency institutions to issue, it is based on specific algorithms, through a large number of calculations, bitcoin economy is used in P2P network.

3. It's virtual currency. It used to be game (recharge) currency. In China, it was used by some swindlers. The appreciation of bitcoin is not equal to the currency in circulation. In the past, one yuan RMB bought a bitcoin and one yuan sold a tea egg. Now bitcoin has appreciated, but this currency can't be exchanged for a tea egg. That is to say, it is just the spiritual appreciation in the dream world. It can't even play the role of digital money. Can WeChat Alipay pay for things sold?

4. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, 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 decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items[ 1-2]
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and take action as soon as possible to completely ban the electronic currency[ 3]
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees.

at the end of October 2013, Hong Kong GBL platform absconded with money, and the whereabouts of more than 20 million RMB were unknown
on the evening of February 28, 2014, the operator of mt.gox, the world's largest bitcoin exchange, announced that all bitcoins on the trading platform had been stolen
the management of Mt. GOx said that after the trading platform was attacked by the Internet in early February 2014, almost all bitcoins traded on the platform disappeared, including about 750000 bitcoins in the user's trading accounts and about 100000 bitcoins held by Mt. GOx itself. According to 28 trading, the loss of about 467 million U.S. dollars
since it is a proct on the Internet, we should always guard against shadow criminals. If they are careless, they can steal everything from you. You know, tigers still have time to nap

the virtual bitcoin mine developed by Zhongben Cong can proce 21 million, which will be completed in 2140. From the first batch of 50 after 2009 to now, more than 13 million have been excavated, and there are still 8 million in the remaining 100 years. It sounds like the method of locking in the total quantity is used to increase the price. Does anyone think that since it is a virtual mine, someone will design a second or countless similar mines in the future. Moreover, with the development of the Internet, the proction process of the virtual currency designed later is more complex and interesting than bitcoin
the popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
in a few years, there will be thousands of virtual e-currency loans. The final result of development will be nothing to lose and all the money will be thrown on the floor

when bitcoin appears, it has already played a role in disrupting international finance. Countries must not watch virtual currency signal to disrupt their own financial markets. As a result, the major league of international financial organizations must crack down on or force the rectification of the virtual goods market, just like international terrorists
in addition, virtual currency has no ability to resist risks at all, and does not have the standard of credit rating at all. At that time, thousands of virtual currencies will return to the starting point of game currency
after a period of false speculation, the indivials or organizations of Zuozhuang have quietly left one after another, and the remaining virtual currency owners will face the end of "poor people kill evil people". Even if they fight hard, it will not help, and the result must be very miserable.

6. It is not only a virtual currency, but also a digital currency and a cryptocurrency

7. As far as I know, there are several ways:

8. The significance of bitcoin mining: distribute the initial bitcoin
opponents of bitcoin accuse mining of wasting a lot of resources to make meaningless coin toss, while supporters take gold mining as an example. For the bitcoin system, the biggest significance of this kind of resource consumption mining is: to distribute 21 million initial bitcoins fairly, just like to consume resources to dig gold, the only way to distribute initial bitcoins fairly is to consume resources to dig bitcoins

bitcoin has thousands of plagiarists, competitors and improvers because of its open source code. Generally, those who simply and imitate bitcoin are called Shanzhai coins, and those who add certain new features to bitcoin are called competitive coins. Some coins add other functional moles such as smart contract to bitcoin, and call themselves "second generation coins". These thousands of coins try all the initial coin distribution modes you can imagine, such as the average distribution of the initial coin to each Icelandic, the distribution of the initial coin to the nextcoin of 73 crowd funding participants, and the slow distribution of the majority of the initial coin by the developer

but the fairness of all these ways of distributing initial coins is far weaker than the mode of burning money to obtain initial bitcoin, and fairness is the core problem of a monetary system. Therefore, although bitcoin mining consumes a lot of resources, it is a reasonable economic behavior just like consuming resources to mine gold.
