1st virtual currency

1. digital currency is a kind of legal tender, which must be issued by the central bank. Both digital gold coin and cryptocurrency belong to digital currency, which is not a network virtual currency, because it is not limited to virtual space, but is often used for real goods and services transactions, such as bitcoin, Wright coin, bitstock, etc. at present, there are thousands of digital currencies issued around the world

the digital currency launched by the central bank is a national sovereign currency, which is based on the digitalization of RMB. This is a piece of data generated by a complex algorithm, which contains blockchain and encryption technology, making it unique. The payment of Alipay and WeChat is not digital money, but only based on the payment realized by electronic accounts. Compared with the current pattern of "payment transfer collection" with the help of third-party payment, what digital currency needs to achieve is "decentralization", that is, to cancel the transfer link and directly hand over the money from the payer's account to the payee, so as to rece the payment cost in currency circulation

types of digital currency

according to different issuing or consensus mechanisms, it can be divided into four categories:

1, proof of work (POW)

proof of work. The system rewards are obtained through the mining of computing power to complete the issuance and distribution of currency. More work, more gain. Such as bitcoin, lightcoin (LTC)
the advantage is that the mining cost can form a monetary price support to a certain extent, and the disadvantage is that energy consumption and environmental protection are criticized< 2. Proof of stake (POS). Allocate the newly generated currency or interest according to the amount and time of cryptocurrency you hold. Such as dash and Neo
compared with pow, POS is more energy-saving, but it increases the security risk

3. The evolution scheme of delegated proof of stake (dpos)
POS. Similar to the voting mechanism of the board of directors, through the election of representatives to vote and make decisions, n accounting nodes are elected to create, verify, sign and supervise each other. Such as the grapefruit coin (EOS)
the advantage is high efficiency, but the problem is that it presents a semi centralized state

4. POW + POS hybrid mechanism
POW is mainly used to issue currency, and POS is used to maintain the system. For example, PPC

according to the project type, it can also be divided into four categories:

1. Currency category
digital currency issued for the purpose of transfer, payment and value storage. For example, bitcoin, bitcoin cash (BCH), Monroe (XmR), and grin

2. Public chain currency, that is, the digital currency issued by public chain projects, is generally the "fuel" for the application projects to run on the public chain. Such as eth, grapefruit coin, TRX and ont

3. Application token, that is, digital currency issued by decentralized application projects, is equivalent to equity or points. For example, OMG (payment application), GXC (data application), 1st (game application)

4. Platform currency, that is, the digital currency issued by the digital currency exchange, is equivalent to equity, points or fuel. For example, BNB, HT and okb.

2. Bitcoin is a kind of virtual currency with more investment in recent years, similar to this kind of virtual currency. In fact, there are many kinds. If you want to really think it has investment value, you need to consider it carefully.

3. Invite NPC to the home and enter the mine at home. A portal will be opened and the teammates will enter

4. Are you talking about the coins in the fire currency exchange
generally speaking, the trading pairs in the exchange are followed by St, which means that the trading volume of this currency is insufficient recently and there is a risk of delisting.

5. Personal opinion:
the program must be a business website.
the scale may be a B2B or B2C regional or provincial business platform website

6. Don't talk nonsense. Tourist attractions and docks, shops near customs accept RMB. Not necessarily in other places

after entering Macao, there are many exchange shops before closing. Change some Portuguese dollars there

the UnionPay card can withdraw RMB, but I haven't tried to withdraw Macao dollar.. I don't know

7.

I'm not sure which version of your QQ game client is

the 2013 version adds a lot of gold coins (game coins) for game task rewards, which can be exchanged for game props, which is different from the full q-coin consumption of props mall

the exchange mall is next to the avatar of the client login home page of version 13

the above is the official introction of lottery, I'd like to add something in Chinese as follows:

toto lottery stipulates that there are two lottery days every week, Monday and Thursday are two lottery days respectively

There are many ways to play toto, and its bonus setting principle is that once winning, the higher the level, the more bonus, and more investment. The most popular are ordinary and System7

1, ordinary: there are spaces on the lottery for you to choose numbers. For example, if you buy six numbers, you need to use a pencil to paint the spaces corresponding to the numbers you choose. If you want to choose seven numbers, you need to paint seven boxes, and eight are the same. In fact, there are some ways to play in China, but toto is 6 out of 45, with $0.5 for each note (it is stipulated to buy at least $1.0 for 2 Notes). Draw 7 numbers for each issue. If the 6 normal numbers plus the 1 special number are all right, Congratulations, this is the legendary first prize. The bonus setting is one third of the total prize pool, but not less than $500000. There is no limit on the number of first prize winners, and the bonus is shared equally by all winners. By analogy, five basic numbers plus one additional number are the second prize

2, System7: the face value of the lottery ticket is $3.5 each. You should choose 7 numbers randomly from 1-46 numbers, including 6 normal numbers and 1 special number. Winning the lottery does not require the number sequence, but it can not be repeated. If you are not sure, you can also give the number to the lottery machine. After the lottery, if you guess three normal numbers plus one special number, you will win the lottery. The minimum prize is S $30. In addition, there are high-grade lotteries such as system8, 9, 10, 11, 12 and roll. The higher the grade, the more expensive the bet. Maybe these lotteries are set for specific consumers. The following is a lottery winning situation map, for reference
