1.
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million

monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform mining: users can explore the computing power of different hardware on many platforms
2. 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
digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

3. 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.

4. It shows that the total amount of this kind of digital currency is relatively large, and the total amount of many digital currencies is as high as 10 billion. The circulation of some MLM coins is not constant and can be increased or split at will. Moreover, there are many different digital currencies in the world, and the number of each digital currency is very considerable
the well-known digital currencies in the currency circle include bitcoin, Ruitai coin, Laite coin, doggy coin, etc.

5. Chinese digital currency should refer to Chinese currency, the specific amount of this currency is not clear. However, many things of this kind of coin are fabricated, not real. And its related companies are mostly forged. Now the Chinese currency has basically disappeared, it is estimated that it should be dead
is it a reliable currency? Just compare it with the mainstream currencies such as bitcoin, Leyte, decent and ether.

6. At present, these currencies are all classified as MLM currencies in China, so it is not recommended to participate in them.
7. The total amount of money in DCEP is not constant
why
let's take a look at the current definition of DCEP
Digital legal tender
in addition to being different from legal paper money in carrier, it has the same function as paper money: value scale, circulation means, payment means and value storage
this is also the function of paper money
the issuance of DCEP is based on 100% reserve and will circulate with cash currency, that is, M0 issuance
although the central bank's digital currency was slowly launched after the rise of blockchain technology, it is not pure blockchain technology, but only uses some technologies related to blockchain
we all know that the commercial application of block chain technology still faces many problems, such as concurrency, data storage and so on
a country with a large population like ours, if we use blockchain technology in a strict sense, it will not be able to carry it at present<
Wanxiang blockchain analysis:
from the information disclosed by the people's Bank of China, DC / EP does not use the real blockchain like Libra
although digital currency is not a token in the blockchain, it is similar to the token in the blockchain in the key features of non double flower, anonymity, unforgeability, security, transitivity, separability and programmability
therefore, DC / EP still belongs to token paradigm rather than account paradigm
the central bank is responsible for the maintenance of the DC / EP issuance registration subsystem, which is centralized and does not need to run consensus algorithm, so it will not be subject to the performance bottleneck of the blockchain
in DC / EP, blockchain is used to confirm the right registration of digital currency and plays an auxiliary role
each country's base currency issuance is increasing every year
therefore, the central bank's digital currency improves the bearing property of money. Paper money is naturally suitable for the atomic world, and digital currency is more suitable for the consumption scenarios in the bit world
the supply is definitely the same as that of the previous monetary system, increasing every year.

9. Digital currency is an alternative currency in the form of electronic currency. It is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community
it 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, lightcoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography.
