digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank

Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
2. The value of a digital currency can be measured by the following methods:
1. The market depth of a digital currency, such as bitcoin and Leyte, is very deep
2. The application scenarios of a digital currency, for example, the digital currency on the coin Ying China platform will correspond to the corresponding physical assets, which are regarded as the digital currency of assets
3. The social recognition of a digital currency, bitcoin, has been widely recognized in the world
What do you mean by value? Put aside the phenomenon to see the essence, it is not gold, is a pile of characters, at present may be the so-called value is fried money, waiting for the next dish man high price take away! I do related services for blockchain projects. When we meet powerful customers who issue coins, even we will buy some. There are too many kinds on the market. I'll teach you to simply distinguish them. After all, they can filter out a large amount of junk money
what is the main body of issuing digital currency
are the relevant legal documents complete
have you ever prepared a case
what kind of exchange is it
what is the publicity effort
How about the packing
this method can be used to judge a lot of tokens. The strength is all reflected in the issuing of coins, one day, one place. Let's not say what the market will be like in the future. Even if it's money circling and running, the one with more investment will run slowly, and even if it's done well, it won't run in the long run
bitcoin is so powerful. Behind it is how many powerful consortia have smashed such a thing through years of promotion and money burning. In the short term, almost no virtual currency can replace its position.

4. The word "digital currency" may be quite strange, but many people have heard of "bitcoin", which has been very popular in recent years. Oh, it's it. But it is, and it is not. And listen to this beginner
it is also closely related to Internet technology and has the attributes of payment and circulation. The central bank's "digital currency" is closely related to bitcoin. But bitcoin is a kind of digital currency, but digital currency is not just a form of bitcoin. Although the central bank's "digital currency" veil has not yet been lifted, there must be many differences with bitcoin
first of all, the issuers are different
most currencies have an issuer. For example, RMB is printed and issued by the central bank. But bitcoin does not have a centralized issuer. It is generated randomly based on an algorithm. Anyone can mine, buy, sell or receive bitcoin
secondly, the acquisition methods are different
bitcoin is the result of unremitting "mining" by some people who master the algorithm. These real it experts need to search for 64 bit numbers by computer, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network and obtain the corresponding bitcoin
but the digital currency issued by the state is bound to face the people of the whole country, rather than some network experts. When the country strives to achieve the goal of Inclusive Finance, how can it only tailor a currency for Internet experts? The national version of "digital currency" is bound to help the realization of Inclusive Finance, facing the most extensive groups.

5. Watch maintenance
(1) when wearing a watch, the sweat on the hand is corrosive to the watch case. The all steel case has better corrosion resistance because it is made of nickel chromium alloy, and the half steel case is made of copper. It is easy to corrode e to long-term contact with sweat. It is necessary to wipe away the sweat with a soft cloth or pad a plastic watch holder to prevent it from being eroded by sweat
(2) do not open the back cover of the watch at will to avoid st entering the movement and affecting the normal operation of the watch
(3) do not put the watch in the wardrobe with camphor pills to avoid the deterioration of the watch oil
(4) don't put the watch on the power amplifier, stereo or TV to avoid magnetization
(5) the watch that is not worn for a long time should be wound once a month, while the watch with automatic movement should swing back and forth for a few minutes or be worn on the wrist for a period of time to make it wind up automatically. So that the parts will not be at rest for a long time to ensure the operation performance of the meter machine
(6) if an ordinary mechanical watch is wet, dry cotton can be pressed on the watch and baked with 40 Watt electric bulb for 5 minutes, then the moisture in the watch will be evaporated completely. If the quartz electronic watch is damp, a few small pieces of calcium chloride can be taken and wrapped with gauze; Then open the cover of the electronic meter, put the wrapped calcium chloride and the electronic meter into a plastic bag or glass bottle without air leakage, and seal them. Generally, the moisture can be removed in about 3 hours to make the electronic meter return to normal. For the surface seriously affected by moisture, the time of absorbing moisture can be extended appropriately
(7) when the watch is received and the outer package is removed, the box used to protect the watch must be kept. These watch protection boxes can provide the safest protection for the watch when it is not fit to wear, so it is absolutely necessary to keep the box. It is suggested that when the watch is not worn on weekdays, we should form the habit of putting it in the box, which can greatly rece the risk of watch damage
(8) it's better not to wear the same watch every day, but to prepare several different watches for alternate use. In addition to enriching personal modeling, it can also avoid st and body dirt all concentrated on the same watch. For leather watch strap, more care should be taken to avoid frequent wear and tear caused by daily use. Even if the surface is new, the watch will look very old
(9) don't sleep with your watch on your wrist. If your watch is a luminous watch, it will bring adverse effects on your body. This is because the luminous material on the pointer and dial of the luminous watch is mainly a mixture of radium and zinc sulfide. The ray emitted by radium can stimulate the crystal of zinc sulfide to emit light. When you sleep, if you wear a watch, your body will be exposed to radium radiation for eight to nine hours, which is harmful to your body. Therefore, before going to bed, it is best to take down the luminous meter and put it on the table
(10) surface modification. After many lines have been scratched on the watch cover, you can first drop one or two drops of water on the watch cover, and then squeeze a little toothpaste to wipe it. Then you can remove the lines and make the watch cover look like new.
