How to carry bitcoin abroad
Bitcoin is a kind of P2P digital currency
reasons for blocking:
1. Vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
The transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed The price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading4. The public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. 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 the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency 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 millionbitcoin 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
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
Transaction mode of bitcoin
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions
I can't buy it
the price of bitcoin rises and falls suddenly, which is very similar to the stock in the game Monopoly 4 played when I was a child, but I don't recommend you to buy it
The reasons are as follows: when we make any important financial decision, we must distinguish between investment and speculation it's just like sleeping, whether you sleep with your girlfriend or with your girlfriend's best friend is a matter of two natures
some inconvenient words are written in the public micro signal "Wu Handi ID:whdkad" (WeChat ID:whdkad), the official account replied "useful" with surprise. strong>
bitcoin fell to $903 on January 10, down to 17% from the peak of $1091 on January 4. The direct reason is that the people's Bank of China has hinted that they are closely watching the market for irregularities. Given that China's bitcoin trading accounts for about 99% of the total trading volume of global exchanges tracked by bitcoinity, it's not surprising that China's regulatory actions are enough to drive bitcoin prices down
1 China's enthusiasm for this cryptocurrency is misplaced. Last year, China's foreign exchange reserves fell by about $320 billion. Given that capital is still flowing in under trade items, the actual scale of capital outflow may be larger. The current scale of the whole bitcoin market is about 15 billion US dollars, which is too small to allow a very small amount of money to leave China
rather than regard bitcoin as a channel for capital outflow, it is better to regard it as the latest type of investment bubble in China. Just as the stock market bubble in 2015 and the precious metal bubble in early 2016, the rise in prices was initially based on fundamentals. For bitcoin, this is based on the demand of Chinese households for offshore capital. With the influx of speculators holding a lot of money, prices soared. In the end, the regulatory crackdown and the carnival ended - until the next round.
If you encounter bitcoin extortion email, you should first pay attention to the email title, form a good habit of reading the email title, and never open the email sent by unfamiliar people. If the unfortunate point opened, then do not follow the instructions of the swindler remittance, should immediately call the police, let the network police involved, so that we can quickly find criminals
bitcoin e-mail blackmail is really terrible, but we should calm down when we encounter bitcoin e-mail blackmail. Although this kind of blackmail fraud only exists on the network, it poses a threat to real property. We must deal with it carefully
extended information
bitcoin blackmail is a virus Trojan horse that will enter the mailbox. When users click on the email, they will find that the email page has a countdown

absolutely impossible
you can imagine this picture: payday is coming, your cold wallet has received 0.05 bitcoin, according to the bitcoin 60000 US dollars, you have earned 3000 US dollars this month, a total of 20100 RMB! You are very happy, just as you are going to have a big meal to reward yourself, bitcoin suddenly plummeted from $60000 to $50000, and it is still falling!! Your 0.05 bitcoin is still so much, but your income instantly reced to 16250, nearly 4000 yuan evaporated, not only that, but also the amount continued to decline with the naked eye!! At this time, I'm afraid no one would like to invite you to a big meal. Instead, I nervously took out my mobile phone and quickly sold bitcoin! When the transaction is completed and RMB 16000 is paid to your account, you will finally relax...
so why is bitcoin easy to store money and transfer assets? This is determined by its design principle. Professional knowledge is too complex. In short, bitcoin is a code city that can't be broken by hackers. All users involved in bitcoin trading in this city can't trace their real information through any technical means. Therefore, bitcoin has become a pure land of assets that governments can't control. In this city, your private property will always be yours, No one wants to take it away. If you forget your password, it will be miserable, because you don't want to take back your own bitcoin. It will be stored in this city forever. Therefore, the extreme security and secrecy of bitcoin make it easy for private property to completely get rid of the control of sovereign states, so it is reasonable for governments to study regulatory methods, because bitcoin is the most powerful in history, which can fight against the country's enemies economically
