How to transfer money to BTC wallet address
By using secure encryption technology to store digital currency, you only need to have a contract address to transfer the currency. The function of this wallet allows you to put the currency in your wallet when you don't use it, which is higher than the security factor in the exchange
wallet is actually used as an address protocol, because all transactions on the blockchain are recorded in the whole network. Every bitcoin transaction to an address is recorded in the whole network and cannot be tampered with. When bitcoin arrives in your wallet, everyone can see the record to prove it
unlike most traditional currencies, bitcoin is a digital currency. Therefore, the method of this kind of currency is completely different, especially when it is obtained and stored. Because bitcoin doesn't have any physical shape or form, it can't be stored anywhere technically. Instead, it is the private key used to access your public bitcoin address and sign transactions that need to be stored securely. The combination of the recipient's public key and private key makes bitcoin transaction possible
there are several different forms of bitcoin wallets, which can meet different needs, and are different in security, convenience, accessibility and so on
paper wallet
a paper wallet is essentially a document that contains a public address and a private key that can be used to receive bitcoin, allowing you to spend or transfer bitcoin stored at that address. These are usually printed in the form of QR codes so that you can quickly scan them and add the key to your software wallet for transactions
paper wallets can be generated using services such as bitaddress or bitcoinpaperwallet, allowing users to create completely random bitcoin addresses and private keys. The generated document can then be printed, some of which offer tamper proof design, and even can choose to order holographic tags and use them
the main advantage of banknote wallet is that the key will not be stored in any place in digital form, which makes it completely free from hacker attacks. It can record the malware users hit and basically any form of digital theft. However, some precautions still need to be taken when creating wallets
obviously, before generating a paper wallet, you need to make sure that no one is watching you. To eliminate the risk of any spyware monitoring activity, it is recommended to use a clean operating system running from a USB flash drive or DVD, such as Ubuntu
in addition, once the paper wallet is set up, the website code should be able to run offline, which allows you to disconnect from the Internet before actually generating the key. Finally, use a printer that is not connected to the network
in addition, it is very important to know that you are printing valuable personal information on a piece of paper. Therefore, you need to take some measures to protect that piece of paper. For example, it is suggested to put it in a sealed plastic bag to prevent water stop, moisture and general wear. Some people like to laminate it and store it in a safe, storage box or entrust a lawyer to handle it
physical bitcoin
physical bitcoin usually preloads a fixed number of BTCs, and the intention is that as long as the private key remains hidden, it cannot cost its value. This is usually achieved by implementing tamper proof seals
bitbill's first proct was like a credit card, but most of its subsequent substitutes were shaped into a round medal. Mike Cadwell, a cryptocurrency enthusiast nicknamed "casascius", created the first popular casascius physical bitcoin in 2011
the private key is hidden under the strippable hologram, and when it is removed, it leaves the tamper proof mode. In exchange, the coin lost its numerical value. Since then, there have been several new coin makers
physical bitcoin is a very convenient way to store your funds more safely, which is very useful in offline transactions. Most importantly, they have recently become a valuable collection. However, the main drawback is serious security issues
in November 2013, Mike Cadwell was asked to stop the operation of the financial crime enforcement network because his work was considered to be a money sender. The rules of the campaign were so overwhelming that he had to stop selling items containing digital bitcoin. Since BTC is still a legal gray area in many countries, these items may even be considered counterfeit by the authorities
mobile
BTC is an indispensable tool for those who actively use bitcoin every day to pay for goods or trade face-to-face in stores. It runs as a smartphone app, stores your private key and allows you to pay for things directly from your phone
in addition, some applications enable users to use their smartphone's near-field communication function, which means that they can simply click on their phone to oppose readers without having to provide any information at all
any complete bitcoin client needs to access the whole blockchain ledger, which is growing and needs several thousand megabytes of storage space. Therefore, mobile wallet uses simplified payment verification (SPV) technology. They only apply to a very small subset of the blockchain and rely on trusted nodes in the bitcoin network to ensure that they have the correct information
although bitcoin storage is a convenient mobile solution, mobile wallet is vulnerable to hackers. In addition, if someone just accesses your mobile device, you may lose control of the wallet. There are a variety of bitcoin wallet applications running on Android devices. Apple banned bitcoin wallets from the app store in February 2014, but withdrew its decision a few months later
Web wallet
Web wallet stores your private key on the server of the company providing such service. The server is always online and controlled by someone else. Different services provide different functions, some of which connect to mobile and desktop wallets to your address on the device you own
very similar to mobile wallet, e-wallet enables users to access their funds anytime, anywhere through any device connected to the Internet. But unless implemented properly, the organization that runs the site may access your private key and take full control of your money. In addition, some e-wallets operate on the basis of exchanges, and some exchanges close down and escape users' funds
Desktop wallet
Desktop wallet has been downloaded and installed on your computer, and your private key is stored on the hard disk. By definition, they are more secure than online and mobile wallets because they do not rely on third parties for data and are more difficult to steal. They are still connected to the Internet, which makes them inherently insecure. But desktop wallets are a great solution for those who trade a small amount of bitcoin from their computers
Desktop wallet has many different choices to meet different needs. Some focus on security, some focus on anonymity, etc
Hardware
Hardware wallet is a unique bitcoin wallet, which can store the user's private key in a secure hardware device. This is the safest way to store any amount of bitcoin, and there is no verifiable event that money is stolen from the hardware wallet
unlike paper wallets, paper wallets must import software at some time, and hardware wallets can be used safely and interactively. In addition, they are not affected by computer viruses, and the stored funds cannot be transmitted to output devices in clear text. In most cases, their software is open source
some hardware wallets even have screens, which adds another layer of security because they can be used to verify and display important wallet details. For example, the screen can be used to generate recovery phrases and confirm the amount and address of the payment you want to make. Therefore, as long as you invest in a real equipment with good reputation made by a reliable and competent manufacturer, your funds will be safe and reliable
bitcoin wallet and security
possible problems:
capture malware. Malware can scan your disk and find your private key. In a few seconds, all your bitcoins will disappear. Trojan can encrypt all the files on the hard disk. After that, it may find all the links to your wallet, realize how much money you have and ask for the exact amount of bitcoin to decrypt your hard drive
virtual exchange can use your money to escape. You can lose the laptop or mobile phone on which the wallet is installed
suggestions:
< UL >avoid using any wallet that needs Internet connection; Please use the refrigerated option instead
check everything carefully. For example, you can receive an email from blockwallet, but it's actually from blockcwallet, and if you authorize, your bitcoin will disappear immediately
bitcoin wallet is a kind of software complying with bitcoin network protocol, which can be used to store, send and receive bitcoin< There are three types of bitcoin wallets:
bitcoin client wallets, bitcoin web wallets, bitcoin mobile phones and pad wallets
bitcoin
trades directly through the wallet. Detailed can go to cnfol bitcoin network to learn how to trade, I don't know.
by 2140, the total number of bitcoins was 21 million. I suggest you buy it< In 2009, a mysterious hacker named Satoshi nakomoto first proposed the concept of bitcoin, and described a method of using computer networks to create an unmanaged "secret currency". Unlike other virtual currencies, bitcoin is not issued by a company or a central bank, nor linked to any real currency, but can be used to buy goods and services in the real world. In essence, it can be seen as a small string of encrypted code quickly transmitted and stored in the electronic wallet on the Internet. Just as the P2P networks such as Napster and Skype once made the record instry and telephone instry into a mess, bitcoin, which challenges the modern monetary and financial science, is also based on P2P - the same as our commonly used BT download technology. The advantage of P2P is to ensure that no institution can manipulate the value of bitcoin or increase the supply to create inflation. In a huge P2P network, bitcoin has a special algorithm, which proces about 300 bitcoins per hour. This output is automatically adjusted by the network. Because you can't control most of the network nodes, you can't modify the algorithm of each user to speed up the money proction. Figuratively speaking, bitcoin is "mined" by computers all over the world. If you want to get bitcoin, you just need to install mining software, and your computer will start to do a lot of calculations, which is mining. No matter which computer is used to mine, it is easy to get 50 bitcoins in the early days of bitcoin. As early as January this year, 50 bitcoin was not worth $15, but on June 9, a bitcoin was worth as much as $29.55. If you trade them, you can get back $1500 of real gold and silver. Now, however, mining requires high-performance computers, and some developers involved say that it is estimated that an ordinary laptop will work for five years to get a bitcoin. Why is that? We have to start with the currency itself. Economics tells us that money exists because of transactions. The value of bitcoin lies in the transaction itself. In order to transfer bitcoin from one account to another, there must be a secure channel. To create a secure channel, a lot of energy will be consumed. Therefore, the whole bitcoin user group should reward the mint (50 bitcoin). In other words, he succeeded in mining. Mining, in essence, is the process of creating new blocks (each block contains 50 bitcoin) on P2P network. In short, the software algorithm determines that it is difficult to create a new block that is recognized by the whole network. If there are more participants, the new block will be generated more slowly. Just like mining, with the depletion of the most accessible resources (assuming no newly discovered mineral deposits), the supply will graally decrease. According to the algorithm, each block can only generate 25 bitcoins by 2013, 12.5 bitcoins by 2017, and so on. By 2030, the total number will stay at a platform, about 21 million. Graphically, this will be a flat curve. Reality also proves this point. As the value of bitcoin rises and the number of participants increases, mining becomes more and more difficult. At the forum, miners discussed how to use dry ice and liquid nitrogen to cool computers, increase CPU frequency and speed up mining software, or customize top computer graphics cards and improve network speed to proce more bitcoin. According to the guardian, someone was mysteriously mining at home, and even was suddenly attacked by the police, who mistook him for drug trafficking. Recently, Symantec, a digital security company, discovered a new trojan virus. This malicious program, coinbit, is used to steal numbers, so that hackers can easily break into users' bitcoin wallets and steal their contents. Before the June 19 incident, members of the lulzsec hacker group and anonymous team had discovered that there was a better way to mine - to use someone else's computer. These hacker groups are famous for their server attacks mainly relying on botnets. Some members found that some miners actually use their botnets to mine. The miners are also said to be hackers, who have used botnets to control more than 100000 computers. With the scale of the current network, the efficiency of mining can be greatly improved. It is estimated that 400 to 500 bitcoins can be proced every day, and the current value is more than 8000 US dollars (as of June 28, 2011, 1 bitcoin = 16.9 US dollars). There are two groups of people in the bitcoin community. One group denies that someone is using botnet to mine. The other group says that this is a fact and admits that botnet computing has dropped dramatically. An anonymous person said it was clear that there were people who thought that participation in mining would be more rewarding than attacking mining.
First of all, you should imagine a concept of "wallet" in your brain. Your bitcoin is in your wallet. A wallet can contain many... Many addresses. The form of the address is the form
with the bitcoin address generated in the bitcoin wallet, you can receive bitcoin from others, and you can also transfer the bitcoin in your account to the bitcoin address of others. Bitcoin address, like bank card number, has the functions of payment, transfer and withdrawal. However, when transferring money, you can only transfer money by knowing someone else's bitcoin address
if we simply compare a bitcoin wallet to a bank card account, then the address of the bitcoin wallet can be regarded as a bank card account number. The difference is that bitcoin addresses can not be stored on the network, but also exist independently of your wallet
bitcoin address is a string of 26 to 34 letters and numbers. It looks like a lot of messy code. To put it bluntly, it's just like your bank card number. All transfer records of each bitcoin address can be checked through blockchain query, which is open and transparent
address generation of bitcoin Wallet: 256 binary digits are randomly selected to form the private key, and then the address is generated by encryption function. This generation direction is unidirectional. That is, you know that the address cannot be decrypted to calculate the private key. At present, the computing power of human computer can't be cracked, so you can publish the address on the Internet with ease

the transaction cash withdrawal of dog coin, Ruibo coin, Puyin and other counterfeit coins will not be affected. The main purpose of restricting withdrawal is to comply with the anti money laundering laws and regulations of the central bank.
first, if the hardware is damaged, it may also cause frequent crash. Mobile phone is a precision electronic proct, and its circuit must work normally in a relatively stable environment. If the mobile phone often works in a humid environment or is strongly shocked by the outside world, It may crash.
for example, sometimes when we accidentally drop our mobile phone on the ground, it may crash. So we must treat our mobile phone kindly and handle it gently; Don't let the mobile phone get into the water, try not to use the mobile phone in the humid environment.
usually, if we operate the mobile phone improperly, it will also cause the mobile phone to crash. Especially when we are sending short messages, if the speed of key operation is too fast or we are bombarded by short messages continuously in a short time, the CPU load of the mobile phone is too large, and the heat generated by the CPU can't be emitted in a short time, Therefore, when we use the mobile phone, we must pay attention to the operation; Besides, try not to disclose your mobile phone number to avoid short message bombardment.
in addition, there are other factors leading to the crash e to hardware problems, such as the aging of hardware, the bad use environment of mobile phone, etc.
Second, software problems
are mainly caused by fatal bugs in the software design of mobile phone. For example, When the mobile phone runs a program, if there is a logic error between the subroutine and the main program, every time the mobile phone runs to the program, there will be an instruction error, which is a bit like the illegal operation in the computer. At this time, there may be a crash. The crash caused by the bug of the software generally has such characteristics: whenever it runs to a certain command, it will cause a crash, That is, every time you perform the same operation, there will be a crash.
if your mobile phone always crashes like this, it can be preliminarily determined that it is e to the software problem. To solve such a crash, you can generally upgrade the software. Now all major mobile phone manufacturers have customer service centers, which provide free software upgrade services, Such an upgrade can only upgrade the software version, and the function of the mobile phone will not change after upgrading. However, some software bugs are solved ring the upgrade, which reces the probability of crash. Now many DIYer mobile phones like to upgrade the software of the mobile phone, which causes instability to the mobile phone, so it's best to go to the customer service center to upgrade the software of the mobile phone, If you upgrade yourself, please make a backup in advance, so as to avoid the software can not be recovered after the upgrade failure.
in fact, the mobile phone crash is as normal as the computer crash. As long as we treat it correctly, there will not be so many people complaining about their mobile phone crash again. But if your mobile phone often crashes, you should pay attention to it, It's better to send your love machine to the customer service center for maintenance.
