wholesale fashion jewelry los angeles california Bitcoin is a type of electronic currency/network virtual currency.
Bitcoin: Also known as "bit gold", it is a kind of online virtual currency. Netizens can use Bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. The situation of reality items.
The Senator Joe Manchin, Senator of West Virginia, issued an open letter to multiple US federal government regulatory authorities on February 26, 2014. It hopes that relevant institutions can encourage illegal activities and disturb finance on Bitcoin The status quo of order is attached to it, and it is required to take action as soon as possible to completely block the electronic currency.
starting from 12:00 noon on January 24, 2017, the three major Bitcoin platforms in China officially began to charge trading fees.
Extension information:
Currency characteristics:
1, decentralization: Bitcoin is the first distributed virtual currency. The entire network is composed of users and has no central bank. Decentralization is the guarantee of Bitcoin's security and freedom.
2, circulation of the world: Bitcoin can be managed on any computer accessing the Internet. No matter where he is, anyone can dig, purchase, sell or collect Bitcoin.
3, exclusive ownership: control the Bitcoin requires a private key, it can be isolated and stored in any storage medium. No one except the user can get it.
4, low transaction fee: You can remit Bitcoin for free, but in the end, the transaction fee of about 1 bit of a bit of transaction will be charged to ensure the faster execution of the transaction.
5, no hidden cost: As a payment method from A to B, Bitcoin does not have a tedious limit and procedures. Know the other party's Bitcoin address can be paid.
6, cross -platform mining: Users can discover the computing power of different hardware on many platforms.
Bitcoin advantages:
1, completely decentralized, without issuing agencies, it is impossible to manipulate the number of issuance. Its distribution and circulation are implemented through open source P2P algorithms.
2, anonymous, tax -free, supervision.
3, robust. Bitcoin depends entirely on the P2P network and has no distribution center, so it cannot be closed outside. Bitcoin prices may fluctuate and collapse, and multi -country governments may announce it illegal, but Bitcoin and Bitcoin's huge P2P networks will not disappear.
4, no borders and cross -border. Cross -country remittances will pass through layers of foreign exchange control institutions, and transaction records will be recorded by multiple parties. But if you use Bitcoin transactions, enter the digital address directly, click the mouse, and wait for the P2P network to confirm the transaction, and a lot of funds will pass. No cross -border transactions will be left without any management and control institutions.
5, the cottage is difficult to survive. Because the Bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, and re -compile to create a new P2P currency.
but these cottage currencies are very fragile and are easily attacked by 51%. Any individual or organization, as long as it controls a 51%computing power of a P2P currency network, can manipulate transactions and currency values at will, which will constitute a devastating blow to P2P currency.
The cottage coins are dying on this link. The Bitcoin network is already strong enough. If you want to control the 51%computing power of the Bitcoin network, the number of CPU/GPUs required will be an astronomical number.
Bitcoin disadvantages
1, the vulnerability of the trading platform. The Bitcoin network is strong, but the Bitcoin trading platform is fragile. The trading platform is usually a website, and the website will be attacked by hackers or closed by the competent authority.
2, long transaction confirmation time. When the Bitcoin wallet is installed for the first time, it will consume a lot of time to download the historical transaction data block. In Bitcoin transactions, in order to confirm the accuracy of the data, it will consume some time, interact with the P2P network, and get the transaction after being confirmed by the entire network.
3, the price fluctuates greatly. Due to a large number of speculators involved, the price of Bitcoin exchanged cash like a roller coaster is ups and downs. Make Bitcoin more suitable for speculation, not anonymous transactions.
4, the public does not understand the principle, and the resistance of traditional financial practitioners. Active netizens understand the principle of the P2P network and know that Bitcoin cannot be manipulated and controlled.
But the public does not understand that many people can even distinguish between Bitcoin and Q coins. "No issuer" is the advantage of Bitcoin, but from the perspective of traditional financial practitioners, the currency of "no issuer" is worthless.

engraved wholesale jewelry tags "Understanding Bitcoin from Multidimensions" Recently, with the mining, the graphics card is out of stock globally, and many netizens have begun to pay attention to Bitcoin, but they know very little about Bitcoin. Although there are many popular science articles on Bitcoin on the Internet, it is difficult to understand the true meaning of Bitcoin without relevant financial knowledge.
So today I will try to introduce the principles of Bitcoin in the most straightforward text, and why Bitcoin generates value such as value, so that everyone will be more intuitive to this "virtual payment system".
r
1, Bitcoin Origin
wants to fully understand the origin of Bitcoin, and I have to mention the existing financial system.
Is know that currency itself does not have value. At first, humans used items to transaction in the form of objects, but there were many inconveniences that it was difficult to change to the items they needed. So the currency came into being. Through the intermediary of the currency, different items can be priced according to the degree of rarity and simplified the transaction process.
Although there are many benefits to currency transactions, there is also a fatal disadvantage, which is centralization. 100%of the existing currencies around the world are issued or abolished by the state central bank, and ordinary people cannot participate in currency issuance or the account of the central bank. If the central bank continues to issue currency, the currency in people's hands will continue to dilute and reduce the purchasing power of the currency.
It is by no means alarmist. Such incidents in some countries in the world have occurred.
For example, Zimbabwe, in recent years, a large number of government super currency has led to the collapse of Zimbabwe's economy, and finally he had to introduce the US dollar into a local legal currency. Zimbabwe economists are considering Bitcoin substitution.
For example, India, Indian officials suddenly announced on November 8, 2016 that the noodles were 500 rupees (worth $ 7) and 1,000 rupees ($ 15). 85%of the property instantly became waste paper.
In order to solve this problem, Bitcoin's father, Nakamoto, proposed a decentralized concept in 2009, that is to say, the issuance of currencies on open source software and constructing the P2P network on it to create a decentralized payment system Essence Many readers don't understand this, what is decentralization?
What is P2P network?
We use the popular WeChat payment as an example in China. Although WeChat and Bitcoin are the same virtual payment system, but Every trading of WeChat is performed in the banking system, and the bank is the center of WeChat payment. Decentralization is a point -to -point transaction, which is not affected by any other factors.
P2P network better understands that P2P is the abbreviation of Peer-to-Peer, which is "partner to partner", also known as the peer network. For example, if you download a movie through iQiyi, you transmit the movie from iQiyi server to your computer; and if you download a movie from P2P resources, you can download from other P2P user computers with this movie resources. And if other P2P users need this resource, you can also download it from your computer.
Bitcoin is like this movie. It does not exist in the central server like the central bank, but it exists in hundreds of millions of computers in the world. Since the issuance, no one can control the number of Bitcoin, nor can it be manually controlled by a large number of Bitcoin to control the currency value. Design based on cryptography can make Bitcoin only transfer or pay by real owners, and excellent security.
is not perfect for Bitcoin. There is a fatal defect that makes it unable to become a legal currency. We will talk about it below.
2, how does Bitcoin produce?
First of all, let's take a look at the "blockchain". The core principle of Bitcoin is "blockchain". All block links are blockchain, and any transaction information and transfer records are recorded in the blockchain. It should be noted that the blockchain is stored in the entire Internet, so any bitcoin holder is not worried about the loss of Bitcoin.
Each time in time, the Bitcoin system will generate a random code on the system node. All computers in the Internet can find this code. Whoever finds this code will generate a block, and then get a one. Bitcoin, this process is often called mining. Calculating this random code requires a lot of GPU operations, so miners purchased massive graphics cards to get Bitcoin profit faster, which is also an important reason for the recent outlets of graphics cards.
It people say that there will be more and more bitcoin in this way, is it completely worthless at all? Of course, Nakamoto also thinks of this problem. Here the bitcoin system has another mechanism: that is, Bitcoin has the total amount of total amount Limited, the total amount of the first four years will be generated. The amount of production will be halved every 4 years. It will be generated in the 4th to 8th year, and only the 8th to 12th year will only be pushed. In the end, the total number of Bitcoin generated was close.
The current one Bitcoin based on the current data structure is divided into 8 decimal bits, which is 0., and the minimum unit of miners dug in Bitcoin is 0.
S. Speaking, Bitcoin is like a Jinshan composed of 21 million gold coins. If you want to get it, players need to use the computing power of the computer to calculate a set of compliance based on the existing algorithm compliance. Numbers with specific laws.
of course, these mathematical problems are becoming more and more difficult as the existing Bitcoin increases.
3, why can Bitcoin generate value? What are the disadvantages?
Actually this problem itself is wrong. It has also mentioned that any currency itself does not have value. Currency can make the currency "value", and this "value" is quoted. But now many people believe that Bitcoin can bring wealth to them, so Bitcoin has "value".
. Let's review the characteristics of Bitcoin.
1, the total amount is limited, only
2, anyone can issue Bitcoin, but the difficulty of issuance is getting bigger and bigger
3, it is safer than the central bank currency, and it is almost impossible to be stolen
4, The transaction process is completely anonymous, and cannot track
Based on the above advantages, more and more people are willing to convert their wealth into equivalent value Bitcoin, and at the same time cancel these wealth fiat currency representative power, so the price of Bitcoin began to continue to continue to continue The rise. I believe that the more people in Bitcoin, the more fierce the price of Bitcoin will rise. Of course, a few days ago Bitcoin soared 21,000 yuan and fell to 17,000 yuan. The incident was speculative. The long -term advantage of Bitcoin could not be controlled by speculation. In the end At this stage, the price of Bitcoin fluctuates too much.
It's performance of Bitcoin at this stage, Bitcoin's liquidity level is low and the risk of liquidity is high. Currency.
It plus the total number of Bitcoin, the phenomenon of shrinkage will become more and more serious. Imagine if Bitcoin replace global currency, if one person has 10,500,000 BTCs, in the future, he will have half of the world's property! And pay attention to this wealth is permanent. So it is completely impossible to completely replace the currency.

Bitcoin is essentially a special solution generated by a bunch of complex algorithms. Special solution refers to the group that can get unlimited (but Bitcoin is a limited one) solution. And each special solution can solve the equation and is unique. Popularly: Bitcoin can be regarded as an equation, and this equation has a solution of 21 million, but solving this equation requires huge computing power. If you guess this equation, you can get a solution. This solution is Bitcoin.
2. If the RMB is metaphorically, the Bitcoin is equivalent to the RMB serial number. If you know the serial number on the banknote, you have this banknote.
Bitcoin can be used for cash, can be exchanged for currency of most countries. Users can buy some virtual items with Bitcoin, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, it can also use Bitcoin to buy items in real life.
In summary, you can think of bitcoin as a daily currency, which has certain liquidity
hamsa jewelry wholesale Bitcoin ™ (Bitcoin) is a virtual currency in P2P form. Point -to -point transmission means a decentralized payment system. Bitcoin does not rely on specific currency institutions. It is generated by a large amount of calculation of specific algorithms. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all trading behaviors. The decentralization characteristics and algorithms of P2P can ensure that the currency value cannot be manipulated by a large number of Bitcoin. Design based on cryptography can make Bitcoin only transfer or pay by real owners. This also ensures the anonymity of currency ownership and circulation transactions.
Bitcoin is a kind of online virtual currency, similar to the Q coin category of Tencent. You can use Bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone is Accept, you can also use Bitcoin to buy items in real life. (Better digital currency trading platform is in "currency")
The biggest difference between Bitcoin and other virtual currencies is that its total number is very limited and has a strong scarcity. There are only no more than 10.5 million in the first four years, and the total number will be permanently limited within 21 million. Another thing is that you can use a computer to produce Bitcoin.
Detailed introduction
Bitcoin is an electronic currency generated by open source P2P software. Some people translate Bitcoin as "Bitkin". The concept of virtual currency Bitcoin was initially proposed by Satoshi Nakamoto in 2009. Now Bitcoin is also used to accommodate open source software and constructed P2P networks on which Bitcoin designed according to the idea of Satoshi Nakamoto. Different from most currencies, Bitcoin does not depend on a specific central distribution institution, but uses a distributed database that uses the entire P2P network node to record the currency transa sex. For example, Bitcoin can only be used by its true owners, and only once, the original owner lost ownership of the sharecoin after the payment was completed.
The feature
Bitcoin is designed as the right to allow anonymous ownership and use rights. Can be stored in third -party hosting services. No matter what form, Bitcoin can be sent to any person on the Internet through the Bitcoin address. The distributed characteristics of P2P and the design that does not exist in the central management mechanism ensures that it is impossible for any institution to control the value of Bitcoin or make inflation.
Bitcoin Correct understanding:
The biggest difference between Bitcoin and other virtual currencies is that its total number is very limited and has a strong scarcity. There are only no more than 10.5 million in the first four years, and the total number will be permanently limited within 21 million. Another point is that any Internet users can use computers to produce Bitcoin.
2009 when Bitcoin was born in Bitcoin, each bounty was 50 Bitcoin. 10 minutes after birth, the first batch of 50 bitcoin was generated, and the total currency was 50 at this time. Every 4 years reaches 210,000 areas, the rewards are halved, from 50 Bitcoin to 25, and then from 25 to 12.5. Until 2140 reached the upper limit of 21 million, and the total amount of bitcoin had been dug had exceeded 12 million. The market value exceeds $ 10 billion.
The important features of Bitcoin:
1, decentralized
The Bitcoin network is not controlled by a central government. Each machine mining and Bitcoin transaction process constitute a part of the network and run together. This means that theoretically, any central institution can collapse it through monetary policy.
2, easy to set
The traditional banks need to open a bank account. Establish payment or transfer with merchant accounts. Bitcoin only needs to set up a bitcoin address within a few seconds, which is very simple and fast without charging.
3, anonymous
The user can save multiple bitcoin addresses without any name, address and personal information of other users.
4, transparency
The block details of Bitcoin, you can view the details of each bitcoin address transaction, and there are real -time transaction records. In other words, if the user discloses a Bitcoin address, anyone can view the transaction details of the address. But I don't know who the user is.
5, low transaction costs
The international bank transfer, international remittances will charge high costs. But Bitcoin transactions have almost no.
6, speed
The user can transfer to anywhere, can be reached within minutes, and the Bitcoin network 6 confirmed processing.
7, irreversible
Is when the user sends Bitcoin to a Bitcoin address, the transfer of the transfer is irrevocable, unless the payment is sent to you.
8. Global generalability
It, in any country and regions around the world, only places with networks can be used.
9, quantity
The biggest difference between Bitcoin and other virtual currencies is that its total number is very limited and has a strong scarcity. There are only no more than 10.5 million in the first four years, and the total number will be permanently limited within 21 million.
Bitcoin trading costs
The transaction costs are voluntarily generated when people do Bitcoin transactions, because people who want to do transactions can pay in the transaction or it can not be expected, but because the transaction must be necessary Received by people with mining, it includes it to the new block that is about to be created. On the other hand, it is not said that miningers must receive transactions, so the transaction fee has become a motivation for miningers. It ensures that a specific transaction will be included in the next block that is about to be produced.
The transaction costs are processed by Bitcoin absenteeism. When a new Bitcoin block is successfully generated, all the information of the transaction is included in blocks, and all transaction costs are collected by users' creation blocks.
