2. Bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most 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.

Bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals

2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked

4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. 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 the use of cryptography design to ensure the security of all aspects of money circulation

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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 21 million

4. It should be Q coin! Although there is bitcoin abroad, it has not been widely used in China

there is a big resistance to the popularization and application of bitcoin in China, because q-coin is too popular!

5.

At present, there are more than 230 countries in the world. Basically, each country has its own currency, but the value of different currencies is different. Some countries can buy a lot of things with a note, while some countries may not be able to buy a jin of eggs with a basket of currencies

as for the currency with the highest and lowest value mentioned in your topic, we can understand it from two aspects, one is denomination, the other is value

let's first look at the world's largest denomination currency

under normal circumstances, the denomination of most national currencies is basically less than 100 yuan, mainly one yuan, two yuan, five yuan, 10 yuan, 20 yuan, 50 yuan and 100 yuan. However, in some countries, after serious inflation, ordinary currency denomination can no longer meet the needs of proction and life, so they can only issue large denomination currencies to cope with the growing inflation. The most typical ones are Zimbabwe and Venezuela. For example, on June 13, 2019, Venezuela issued 10000, 20000 and 50000 sovereign Bolivar large denomination currencies, trying to curb Venezuela's vicious animal inflation in this way

However, Venezuela's 50000 denomination currency is not the largest denomination in the world at present. The largest denomination in the world should belong to Zimbabwe's currency. At present, Zimbabwe's largest denomination currency is 100 billion yuan. However, in recent years, the largest currency issued by Zimbabwe reached 100 trillion yuan, that is to say, there are 14 zeros behind a single currency

according to the official regular currency, the smallest denomination at present should be about one cent, which is also available in China

next, let's look at the world's highest value currency

if virtual currency is also considered, then the most valuable currency at present belongs to bitcoin, because at present a bitcoin is equivalent to about $10000

of course, bitcoin is only a virtual currency, not used for normal circulation, so it should not be compared with normal currency. If we only consider the national currency in normal circulation, the highest value in the world at present is the Dinar of Kuwait, which is about 22.5 yuan

if we only consider the value of a single note, the highest value of a single note in the world is Euro 500 denomination

As for the currency with the lowest value in the world, I don't think we all know that it is the currency of Zimbabwe< br />

6. Most of the trust in bitcoin comes from the fact that it doesn't need any trust at all. Bitcoin is completely open source and decentralized, which means that anyone can view the whole source code at any time. So any developer in the world can verify exactly how bitcoin works. Anyone can query all existing bitcoin transactions and issued bitcoins at a glance in real time. All payments do not depend on third parties, and the entire system is protected by cryptographic algorithms reviewed by a large number of experts, such as those used in online banking. No organization or indivial can control bitcoin, and even if not all users are trustworthy, bitcoin networks are still secure.
