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

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 currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography

related background:

the emergence of Ethereum is to help users more easily use blockchain technology for application design. According to BARTLIN, the purpose of Ethereum is to create a more general blockchain platform, which can allow users to easily create blockchain based applications and avoid users having to build a blockchain in order to create a new application

generally speaking, the previous blockchain was only a single tool or at most a combination of multi-functional tools, while Ethereum is the smartphone of blockchain, and users can use the smartphone to build any "application" they need. Therefore, BARTLIN said that the application of blockchain is not limited to cryptocurrency. It has great potential and can be applied to all walks of life. It can bring significant benefits to enterprises and organizations of all sizes

5. Electronic money:
electronic money refers to the exchange of a certain amount of cash or deposit from the issuer and the acquisition of data representing the same amount. By using some electronic methods, the data is directly transferred to the payment object, so that the debt can be paid off. Strictly speaking, consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in the electronic devices held by consumers in electronic form. In short, when we deposit money into our bank account, there will be an extra number in the bank account, which means how much money we have saved. In this process, we give the banknotes in our hands to the bank, and the bank adds a number to us, which is our electronic currency<

digital currency:
is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. It can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual space. On January 20, 2016, the people's Bank of China held a seminar on digital currency, announcing that it is developing and striving for the early launch of digital RMB. At the meeting, many experts discussed the overall framework of digital currency issuance, national digital currency in currency evolution, cryptocurrency issued by the state, etc

"the issue of digital currency will make China's economy programmable to a certain extent, and make the economic and financial regulation have a clearer direction, and the whole network distributed accounting mode implemented by digital currency will effectively enhance the credit of China's economy." However, Yao Qian, deputy director of the science and Technology Department of the people's Bank of China and head of the preparatory group of the digital currency Research Institute, also told the media that there is no timetable for the issuance of legal digital currency at present.

6. BNB, ecell and LTC are my favorite. I suggest that you buy them separately and share the risks equally. Don't put the eggs in the same basket.

8. There are six ways to test the authenticity of gold:

1. Visual inspection
1. Check the official mark of gold. They are usually engraved with 999 or 990, or 10K, 18K, 22K, 24K. We don't consider those below 10K, because the gold content is too low. If you use a magnifying glass, you will see it more carefully
2. Ancient gold ornaments do not have obvious official purity marks
3. Fake gold ornaments also have official marks, so further inspection is needed
4. Look for obvious discoloration. Check the wear area of the gold surface, usually at the edge of the gold proct, and check the discoloration there. If the gold color graally disappears and becomes another color, then the proct is only gilded

2. Bromine chemical test
1. Put the gold proct into the alcohol solution and shake it for a while
2. Soak a piece of filter paper with alcohol solution
3. The filter paper turns grey purple
4. Drop 4 drops of bromine-a reagent onto the filter paper. If the filter paper turns white, then the gold proct is real gold
the total test time is 20 minutes< This is a simple test, but it is not a sufficient proof to prove whether it is real gold. You can find a powerful magnet to test
gold is not a magnetic metal. If the proct is attracted by a magnet, it is sufficient to prove that the proct is not gold. But we can't prove that the proct is gold just because it doesn't react to magnets, because there are still many non-magnetic metals< In density test, only a few metals are denser than gold. The density of pure 24K gold is about 19.3 g / ml, which is much higher than that of other metals. Density test is enough to prove that the proct is gold. The higher the density, the higher the purity of gold. Please make sure there are no gems attached to the proct
1. If there is no such equipment, jewelry stores can usually do density test
2. You can put the gold proct into a container full of water, and then test the volume of the spilled water, and divide it by the weight of the proct to get the density of the gold proct. Remember, different gold purities have different G / ml ratios: 14k – 12.9 & # 12316; 6 g / ml 18K gold - 15. 2 to 15. 9 g / ml 18K platinum - 14; 16.9 g / ml 22K - 17.7% to 17.8 g / ml< 5. Bite test
the miner bites the gold to test it. Olympic athletes will bite the "gold" medal when they win the gold medal. How simple the test is
1. Take a bite
2. Check the bite marks. The deeper the bite marks, the higher the purity of gold
in fact, this is not a recommended test, which can damage teeth. What's more, gold will be plated with lead, which is softer< 6. Ceramic scratch test method
1. Use unglazed ceramics. If you don't have this, you can buy it from a ceramic shop
2. If the scratch is black, it means the proct is not gold. If the scratch is gold, it means the proct is gold.
