China has RMB, bitcoin and what else

1.

1. Q coin

Q coin, referred to as QB, also known as QQ coin, Tencent Q coin, etc. Usually its exchange rate is 1q currency = 1 RMB, with Tencent paipai net transactions are generally 10% off

QB is a virtual currency launched by Tencent, which can be used to pay for QQ bank number, QQ member service and other services. Tencent q-coin, through the purchase of QQ card, telephone recharge, bank card recharge, network recharge, mobile phone recharge card, one card recharge card and other ways to obtain

The face value of QQ card is 10 yuan, 15 yuan, 30 yuan, 60 yuan, 100 yuan and 200 yuan respectively

there is another kind of electronic cryptocurrency, qqcoin, which is not related to each other

2. Litecoin

litecoin, abbreviated as LTC, currency symbol: Ł; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization

3, infinite coin

infinite coin (hereinafter referred to as IFC) is a new digital currency, which has more circulation advantages than bitcoin, and fills the short board of bitcoin in the field of commercial circulation and promoting commercial operation. The positioning of unlimited money is to serve the daily life of small transaction payment

one transaction of infinite coin needs three confirmations, each confirmation takes three seconds, and the transaction confirmation speed is very fast. Because bitcoin transaction needs 6 confirmations, which takes about 1 hour, and lightcoin transaction takes 15 minutes, infinite coin is used in daily common transactions, which is more practical

infinite coin was released on June 5, 2013. Based on scrypt POW algorithm. A block is generated in 30 seconds. In the initial block, there are 524288 infinite coins in each block. After that, for every 86400 blocks generated, the number of coins in the block is halved, with a total of 90.6 billion. The difficulty of mining is adjusted every hour

Quark coin is not the currency in real life, it exists safely in the computer of global network

quark network is protected by six most advanced encryption algorithms to ensure that it can become a digital ledger. The whole network uses each of the six functions to generate a proof of work, and the coin maker must "verify" these transactions to ensure that each coin increase is real and effective

only regular computer can participate in ensuring that it can maintain a highly secure peer-to-peer network, which makes it more decentralized

quark coins can only be g up through the CPU of regular computers. In the first 36 weeks, a total of 247605120 quark coins will be g out. Since March 30, 2014, the annual quark coins set at 1050000 can enter the market through "digging", and the block reward will never be less than one, which is currently two

Zetacoin is an open-source digital currency based on SHA-256 algorithm. The initial coin mining is 160 million coins, and the subsequent annual inflation is a better incentive, To keep the hash of the network is not pure transaction cost

The total number of

zetacoin is 160 million, 1000 zets per block and half of 80640 zets per block

2. The number of bitcoin is too small to circulate on a large scale in society. Moreover, its existence is not guaranteed by the national credit, but based on the trust between bitcoin players, so the credit of this "currency" is relatively low
moreover, the number of bitcoin is small, and it is too concentrated in the hands of several big players, which leads to its price instability. This is basically not money. Because as a general currency, an important prerequisite is price stability, otherwise the economic order will collapse.

3. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees

on September 4, 2017, the central bank and other seven ministries and commissions announced that China banned virtual currency trading

on December 17, 2017, bitcoin reached an all-time high of $19850

on November 25, 2018, bitcoin fell below the $4000 mark and is now stable at more than $3000.

in April 2019, bitcoin again stood at the $5000 mark, reaching a new high of the year.

4.

According to the overseas edition of the people's daily, on August 21, the relevant person in charge of the people's Bank of China reported in public that the development of the digital currency system was under way, and the "digital RMB era" was coming

it is reported that at the third Yichun forum of 40 people in China finance, Mu Changchun, vice mayor of CCTV payment and settlement department, said that the digital currency Research Institute under the central government started the development of digital currency system as early as 2018

There are essential differences between bitcoin virtual currency and digital currency. Bitcoin and other "virtual currencies" are not money in essence. Unlike legal tender issued by the state and national credit support, the investment of virtual currency is affected by factors such as tightening supervision and technical problems, and its price often rises and falls sharply, which disturbs the domestic market to a great extent, Even the normal order of the global monetary and financial system

from the perspective of currency circulation principle, in order to ensure the orderly operation of the financial system and macro-control, only the state can exercise the highest power of currency issuance. Therefore, the central bank's digital currency is legal digital currency issued by the central bank based on national credit, which is fundamentally different from bitcoin
