Bitcoin account management
If bitcoin accounts are decentralized, so are hackers. Bitcoin, which uses blockchain technology, is not more secure than bank accounts. On the contrary, it is vulnerable to hackers. So, in the world of virtual currency, how to protect the security of account funds
Secret your private key address
the bitcoin address is the only information needed to define the distribution and transmission end of bitcoin. These addresses are generated anonymously by the user's wallet. Once the address is used, all the transaction history related to it will destroy the confidentiality of the address. Anyone can view the balance and all transactions at any address. Because users usually need to disclose their identity in order to receive services or goods, the bitcoin address cannot be completely anonymous. For these reasons, it is better to use bitcoin address only once, and users must be careful not to disclose the address
When replacing the computer, try to destroy the hard disk of the original computer. Don't save or publish the private key of bitcoin to the cloud, mailbox or collection. If a network administrator writes a regular expression to retrieve the text, he can find all the information and crack the user's account2. Stored in bitcoin wallet
many bitcoin exchanges have been attacked by hackers. If you use the wallet of bitcoin exchange, please use Google's "double authentication" to ensure security. During the development of virtual currency, there have been many cases of bitcoin exchange running away. The exchange owns the private key of the user's wallet, which is not a safe way to save bitcoin
bitcoin wallet has a wide range of customers, which is more secure than the wallet service of bitcoin exchange. No matter what kind of wallet you choose, you should choose a strong password. Don't use the same password as the registered email. At the same time, do not put eggs in the same basket, choose multiple storage ways to improve the security of assets
using the genuine system of bitcoin wallet, regularly updating security vulnerabilities and fixing bugs can improve security. Some studies have pointed out that IOS system is more secure than Android system, because the existing security vulnerabilities of Android system may be relatively easy to be attacked by hackers
3. The most common way to identify phishing sites is phishing sites. Hackers will create a domain name similar to bitcoin website, which may be sent to users through e-mail and other channels. Once users try to log on the website, hackers will record their login information
so be careful before clicking any link. Many browsers have the service of "phishing check". If you carefully identify the domain name of the website, you can identify the phishing website
4. Guard against Keylogger
in addition to phishing sites, the common attack method of hackers is Keylogger. Keyboarding is the easiest way to capture passwords. The deception of key recording software is very high, even the technical house may believe it. In short, a keyboard recorder is actually a script code. Once it is installed on the operating system of the target computer, it will record all the keystrokes on the keyboard and send them to hackers, mostly through FTP
the successful method of introcing Keylogger depends on many factors, including the operating system, the lifetime of keylogger and the anti infection level of target computer. Keyboard recorder is usually injected through web browser. The security vulnerability of the target machine depends on the type of browser it uses; Whether the operating system installed on the target machine is genuine, and whether the operating system is updated with the latest security vulnerabilities and bug fixes
5. Watch out for USB theft program
the software will retrieve your password and login credentials stored in the browser. Once FUD, some stealing programs can be very powerful. In most cases, a steal program is a. Bat file, which can be injected into the target machine online or driven by USB
6. Using proxy and VPN
proxy server and VPN can increase the security of your bitcoin wallet, although most people mistakenly believe that VPN makes them anonymous online. But in fact, VPN only improves the privacy of users. VPN can rece the possibility of hackers accessing the router to open the port, which also means that they are less likely to succeed
7. Encryption and backup wallet
wallet backup is essential to prevent losses caused by computer failure or human error. If a computer or mobile phone is lost, a backup wallet can help retrieve the bitcoin. At the same time to encrypt the online backup, any backup that can be accessed through the Internet should be encrypted
how to back up your wallet? First, close the bitcoin client, then select the backup wallet of the menu file in the main interface, and the wallet.dat file to other hard disk partition, mobile hard disk or U disk
it should be noted that the entire wallet should be backed up, not just the private key. Bitcoin wallet has many private keys for receiving transaction change. If only the private keys of visible bitcoin addresses are backed up, most of the funds may not be restored from the backup. Also, back up your wallet regularly to make sure that all recent bitcoin change addresses and newly created bitcoin addresses are included in the backup
Cold storageoffline wallet is called "cold storage", which is the safest way to save digital currency
cold storage is an offline wallet that is not connected to the network, that is, it will not be attacked by black horse and Trojan horse. However, because the operation is relatively complex and the price is relatively expensive, the price of offline wallet is more than 1000 yuan, which is suitable for users who have a lot of bitcoin and are ready to hold it for a long time
although the operation of cold storage is relatively complex, it is the safest storage method. At present, only cold storage has truly realized the inviolability of personal assets and is not subject to the supervision of others
if you want to know more about bitcoin information, please send me a private message and avoid detours
however, it has not been fully and effectively regulated at present (as of March 6, 2019)
if we understand bitcoin as a kind of "currency", then it is equivalent to US dollars leaving the United States. Usually, after the US dollar leaves the United States, banks in other countries will help manage it. However, it is impossible to count the scattered us dollars that are neither in the United States nor in the hands of banks and other financial institutions. For example, in some areas of Africa where there are no banks, the US dollar is used
these scattered us dollars are equivalent to bitcoin
how to regulate these scattered us dollars
generally, in addition to controlling the issuance of US dollars, US dollar regulation also controls the circulation and usage ports. The Federal Reserve controls the number of new currencies issued each year according to the flow and damage of dollars abroad. At the same time, we should supervise the inflow and outflow of US dollars, so as to keep us dollars in an environment that can be roughly traced, so as to facilitate the issuers to count the total amount, so as to avoid excessive inflation or deflation
in fact, these scattered us dollars exist in some deregulated environments. Although they are out of control, they will not affect the overall economic situation
If anyone wants to influence the international economy through these scattered us dollars, then it must enter the existing regulatory system. In this way, these scattered dollars are regulated
for bitcoin, we can also learn from these forms of regulation
first of all, from the point of view of the issuing end, although the total number of bitcoin is now 21 million, it is also "set before" and cannot be changed
recently, it has been mentioned that the 21 million bitcoin limit should be abolished, which means that the issue of bitcoin is not stable. Therefore, it is necessary to control the issuance of bitcoin from the development end
you need to get inside the development side and become a core developer
Second, monitoring from the circulation link. In fact, this is the most difficult monitoring at present, because the blockchain is anonymous, the user is anonymous, and the receiver is anonymous
even though we can trace the circulation path of bitcoin by technical means (for example, we can know that a transaction is sent from a small house in the United States to a commercial building in Germany), it is only a drop in the bucket for tens of millions of users in the whole environment. How to trace and manage the overall transaction data is a huge problem
you can't know from the transaction data whether the user is engaged in illegal transactions
what should we do? Regulators have come up with a way to bind personal identity information to the user's real name, your exchange account number and bitcoin wallet address. But this is also a temporary solution, because it can only monitor the use of bitcoin in specific situations. An indivial can use multiple bitcoin wallet addresses. You don't know when he will apply for a new one
in terms of circulation, there is also a monitoring system to control the exchange channel between bitcoin and local legal currency. Banks in some regions do not provide financial services for users who exchange bitcoin for legal currency, and some countries and regions prohibit financial institutions from providing bitcoin and local legal currency exchange services
if users secretly exchange huge amounts of bitcoin, some clues can be found through the bank transfer records, so as to crack down on illegal acts in time. As for those who make little trouble, let him go
thirdly, restrict the use. This is relatively easy to achieve. For example, relevant laws have been issued to prohibit the use of bitcoin transactions. Although it's impossible to ban it completely, it's better than letting it run wild All over the world, it seems that what is forbidden is not completely forbidden
for example, before using bitcoin in public, you must use your real name, and you have to pay taxes to hold or use bitcoin
of course, it's OK for users not to do so, so it's better to use its assets in the dark
having said so much, now you know that bitcoin can be regulated, but it's not so well managed. Many measures have been taken, and it seems that they are not effectively regulated. Under what circumstances can bitcoin be effectively regulated? Users consciously report their holdings of bitcoin to the regulatory authorities. The regulatory authorities add some development functions to the bitcoin to achieve supervision, or they don't need to use it, so it doesn't matter at all
in fact, it can't be controlled so strictly, as long as it can't be controlled in the range of big waves. After all, there is light and dark, and there may be no gray space at all
new technology will surely have an advantage when it comes to living now.
How do we know what should and should not be taxed? Now, we have some experts who can help us understand, but if you are involved in cryptocurrency and live in the United States, it will be easier. Laura shin is such a kind and helpful person. She explains how to deal with digital currency and the IRS when it comes to taxation. Her article in Forbes clearly explains the different sources of bitcoin and digital currency. First, all digital monetary assets are regarded as capital assets like stocks and bonds. The IRS calls cryptocurrency an asset in its guidance 14-21
there is only one way to own digital currency or spend it, and that is to start mining. If you succeed in mining some bitcoin, any block reward you may get depends on the amount of bitcoin you get and the market value at that time. It's very important to have the right record, because the value of bitcoin is bound to fluctuate, and you never know how much bitcoin is worth when you pay taxes. The calculation of tax depends on whether it is a long-term or short-term capital gain
do you get a return in bitcoin? The good news is that if you try to save some, and the price of bitcoin goes up, your salary could double. The bad news is that you'll pay income tax on wages and VAT on assets that hold the subsequent gains in bitcoin. However, it is best to record the actual value of legal tender when payment for services is received
if your salary is paid in the form of bitcoin, you may want to spend some in the form of bitcoin itself (for others who own bitcoin by any means). The expenditure of any bitcoin is equivalent to the sale of assets, and the gain or loss will occupy the holding period. So in order to find out the holding period, people have to know which bitcoin they are selling and when they receive a special bitcoin, which is almost impossible unless you use a new wallet for every transaction. A better way is to have a set of predefined rules for all bitcoin revenues and expenditures. Laura suggests the implementation of LIFO or FIFO accounting methods
if you give or accept bitcoin as a tip or gift, it is best to publish or ask for information about the cost base and date of digital currency. If this could be done, it would be easier to calculate capital gains. Otherwise, in the absence of information, people can always explain it in terms of income and get out of trouble. If you are donating to a registered charity, the digital currency unit income from the donation can be written off from the account, which is not taxed. Laura suggests using digital currency donations to rece taxes
when trading bitcoin, it is wise to keep a record of the fair market value on the date of the transaction. If a trading platform or transaction issues a 1099-b report, this will help record the profit and loss. These suggestions will come in handy for those who are already working on bitcoin and want to know how to track the gains and losses of their digital currency.
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. 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 21 million
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< 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 relevant institutions 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
hope to adopt
Today (August 26), there is a of the "Interim Measures for the administration of bitcoin trading activities (Draft for comments)" (hereinafter referred to as the "measures"). The bitcoin platform should be put on record in the central bank, and a third-party depository service for customers' funds should be established< relevant people of the central bank told reporters today that the above report is not true, and the central bank did not release this document
as early as 2013, the central bank and other ministries and commissions have issued a notice to make it clear that bitcoin is not issued by the monetary authority, has no monetary attributes such as legal compensation and mandatory, and is not a real currency. As of today's 12:15 or so, bitcoin prices hovered around 29000
Don't believe false news
