Comparison of advantages and disadvantages of digital currencies

1.

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

2. 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.

3. Compared with the traditional bank transfer, remittance and other methods, dcpro digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment which provides high fees to payment service providers.

Digital RMB is different from paper money, but now digital RMB is graally in everyone's view. Before that, we used paper money. When we got the paper money in our hands, we would feel that money is real. But now, many people don't have this concept of money, and it is because of this that the lives of young people are affected

With the progress of the times and the development of society, people's life has changed a lot. In the past, our money is basically paper money, especially when we pay wages, with a thick pile of money in our hands, we are very excited. And when we use it, we are also careful. When we watch the money decrease one by one, we feel that our life can't continue after the money is used up. Therefore, many people are very careful in their life. But now the digital RMB has replaced the paper currency RMB. As long as people have a mobile phone, they will walk around the world, and they don't need to carry the paper currency

Therefore, we must know how to make rational use of money, whether it's money in front of numbers or paper money. Only in this way can our life become better

The role of digital currency:

1. First of all, the central bank's digital currency can provide a huge data base for monetary policy and macro Prudential policy, so that the regulatory authorities can collect real-time trading books of different frequency and different institutions according to their needs, and it is complete and real. This information advantage can help the central bank use policy tools more accurately and flexibly

Secondly, the central bank's digital currency technology can track the flow of funds and help the regulatory authorities to comprehensively monitor and assess financial risks. Finally, the central bank's digital money technology is concive to the transmission of interest rate of monetary policy. Digital currency technology supports "point-to-point" payment and settlement, which can improve the liquidity of market participants. Only the digital currency of the central bank, which is generally accepted by the whole society, can radiate this advantage to the participants of different financial markets, so as to improve the liquidity of financial markets. This will make the term structure of interest rate smoother and the transmission mechanism of interest rate smoother

extended data:

digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: because it comes from some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough

6. Hello, there's no problem with this graphics card with this kind of hardware.
even if it's live broadcasting, it's no problem. Live broadcasting is mainly about processor and memory. You can satisfy it, but you need to ensure the network speed

7. Mining in Inner Mongolia is deceptive

8. A machining center of about one meter is a relatively large one. This kind of machining center is generally equipped with imported systems, such as FANUC, Siemens, Mitsubishi, etc. the specific price is more than 30 Wan. Different manufacturers also have a certain impact on the price. Shenyang machine tool factory and Dalian machine tool factory are better domestic machining centers, We should choose the machining center according to your actual situation. If you want to buy in Northwest China, we suggest you look for Dongyue machine tool. They all sell the first-line well-known brands in China. They are the general agent of many first-line brands in Northwest China, and the price is relatively favorable. The 850 in our factory was bought from them last year. I hope it can help you
