Pay currency function applies digital currency

1. Usdt is the digital currency anchoring US dollar
DCC belongs to counterfeit currency
and has no value at all

2. Decentralized or cold wallets are relatively safe. The private key is backed up by itself and can be checked on all data links. As long as the private key is not leaked, the assets will not be stolen.

3.

The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods

many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat

extended information:

whether the hardware wallet is safe

the hardware wallet can not guarantee 100% security. For example, if a geek obtains your hardware wallet, it may be cracked violently even if it doesn't know your hardware wallet immediately. It's just one of the safest storage methods compared to other storage methods

of course, there are exceptions, such as you have unlimited brain power and never forget. It's better to save it anywhere than in your own mind

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

5.

There must be radiation from virtual currency mining, including mobile phones and computers, not to mention mining

Mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network

it can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network

this process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin

however, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks

after the last bitcoin issue, mining is still necessary

extended data:

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of display card, which consumes a lot of power

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency

At present, there are more than 100 kinds of digital currency in the world

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly

nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization, which has very high mining efficiency

resources: Network - bitcoin mining machine

the red I point in the picture is the address of Panyu Central Hospital, and the nearest subway station is Panyu Square Station of line 3

7. From the function of bookkeeping, the team of bankable app is very attentive, which is very consistent with the process of digital currency trading
1. A variety of transaction scenarios: currency transaction, legal currency transaction, full withdrawal currency:

currency transaction: mutual exchange between digital currencies. For example, if I buy an EOS with usdt in JYS and directly record a usdt purchase EOS in the currency app, the number of EOS will increase and the corresponding usdt number will decrease in my account book. This function is quite practical
legal currency transaction: record the situation that I directly buy and sell with legal currency, and at the same time, I can see the flow of my legal currency, so that I can know my legal currency investment more clearly
withdrawal process: record the withdrawal process between my different exchanges or wallets
2. Add the digital currency that is not online, so that I can record the currency that I participate in private placement
3. The currency app can automatically calculate: profit and loss of holding currency and total profit and loss of selling currency

(1) the cost and floating income of my existing digital currency make me more clear about the income of my existing currency assets
(2) the bagged income of the sold digital currency
(3) and the total income of the digital currencies I currently hold and have sold
the above three kinds of income can be viewed separately, so that I can make better trading decisions
4. At the same time, the function of [View asset classification] is also good:
(1) you can view the trading income of the currency according to the currency
(2) you can view the asset income according to the storage location (wallet and exchange)
(3) you can search the transaction flow according to the time, asset storage location and currency, Quick search for some of my deals.

8. Not digital money, the third party payment platform, with Alipay.

9. Coinpay wallet is a proct invested and developed by skrill group after studying the current financial situation. It was first launched in 2018. This digital money wallet, coinpay, is developed based on blockchain technology, and is also an important research achievement made by skrill group after entering the blockchain field since 2016. The so-called blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. The consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. A few years ago, bitcoin, which was hot in the coin circle, was also based on blockchain technology. Blockchain is the underlying technology of bitcoin, like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry. On January 20, 2016, the digital currency seminar of the people's Bank of China announced that the research on digital currency has achieved phased results. The meeting affirmed the value of digital currency in recing the issuance of traditional currency, and indicated that the central bank was exploring the issue of digital currency. Blockchain technology itself has been widely recognized, which is one of the important reasons why skrill group has entered the field of blockchain.

10. At present, it has integrated WeChat payment, Alipay, Visa, Master, Dash, GrabPay, Nets and other legal tender payment systems, and supports BTC, ETH, USDT, BCH, BNB and other mainstream digital currencies.
