How to use Bitcoin paper wallet

　　Bitcoin paper wallet is a wallet that prints the private key on paper. It is a way to store Bitcoin offline and also a relatively secure storage method.

　　The steps to use Bitcoin paper wallets are as follows:

　　1. Generate paper wallet

　　Firstly, you need to use a Bitcoin wallet generator to generate a paper wallet. This process usually includes generating a random Bitcoin address and a corresponding private key.

　　2. Print paper wallet

　　Print the generated address and private key on paper, and it is best to print it in the form of a QR code, which can facilitate scanning.

　　3. Store paper wallet

　　Keep the printed paper wallet properly stored, and it is best to store it in a safe place, such as a safe or a password-protected file.

　　4. Use paper wallet

　　When you need to use Bitcoin from the paper wallet, you can use any Bitcoin wallet application to scan the QR code, import the address and private key into the wallet, and then you can use this address for transactions.

　　It should be noted that when using Bitcoin paper wallets, you must ensure that the private key of the paper wallet is not lost or leaked, otherwise Bitcoin may be stolen. In addition, it is recommended to back up the private key regularly to prevent any unforeseen circumstances.

　　In 2008, the global financial crisis broke out, and on November 1 of the same year, a person who claimed to be Satoshi Nakamoto published the Bitcoin white paper ‘Bitcoin: A Peer-to-Peer Electronic Cash System’ on the P2P foundation website, stating his new vision for electronic currency – Bitcoin was thus born. On January 3, 2009, the Bitcoin Genesis Block was born.

　　Compared with fiat currency, Bitcoin has no centralized issuer, but is generated by the calculation of network nodes, anyone can participate in the production of Bitcoin, and it can be circulated worldwide, traded on any computer connected to the Internet, and regardless of where you are, anyone can mine, buy, sell, or receive Bitcoin, and in the process of transactions, outsiders cannot identify the user’s identity information.

　　On January 5, 2009, Bitcoin was born without the control of any central bank or financial institution. Bitcoin is a series of complex codes generated by computers, new Bitcoin is created through a preset program.

　　Whenever Bitcoin enters the mainstream media’s field of vision, mainstream media will always invite some mainstream economists to analyze Bitcoin. In the past, these analyses were always focused on whether Bitcoin is a scam. Nowadays, the analysis is always focused on whether Bitcoin can become the mainstream currency of the future. And the focus of the controversy is often on Bitcoin’s deflationary characteristics.

　　Many Bitcoin players are attracted by the fact that Bitcoin cannot be arbitrarily issued. In contrast to the attitude of Bitcoin players, economists have a polarized attitude towards Bitcoin’s 21 million fixed total amount.

　　Keynesian economists believe that the government should actively regulate the total amount of money, using monetary policy to timely accelerate or brake the economy. Therefore, they believe that Bitcoin’s fixed total amount of currency sacrifices the controllability and, worse, will inevitably lead to deflation, thereby harming the overall economy.

　　奥地利学派经济学家们的观点却截然相反，他们认为政府对货币的干预越少越好，货币总量的固定导致的通缩并没什么大不了的，甚至是社会进步的标志。

　　比特币网络通过“挖矿”来生成新的比特币。所谓“挖矿”实质上是用计算机解决一项复杂的数学问题，来保证比特币网络分布式记账系统的一致性。比特币网络会自动调整数学问题的难度，让整个网络约每10分钟得到一个合格答案。随后比特币网络会新生成一定量的比特币作为区块奖励，奖励获得答案的人。

　　2009年，比特币诞生的时候，区块奖励是50个比特币。诞生10分钟后，第一批50个比特币生成了，而此时的货币总量就是50。随后比特币就以约每10分钟50个的速度增长。当总量达到1050万时（2100万的50%），区块奖励减半为25个。

　　当总量达到1575万（新产出525万，即1050的50%）时，区块奖励再减半为12.5个。该货币系统曾在4年内只有不超过1050万个，之后的总数量将被永久限制在约2100万个。

　　比特币是一种Online casino and How to find it ，数量有限，但是可以用来套现：可以兑换成大多数国家的货币。你可以使用比特币购买一些虚拟的物品，比如网络游戏当中的衣服、帽子、装备等，只要有人接受，你也可以使用比特币购买现实生活当中的物品。

　　2014年2月25日，“比特币中国”的比特币开盘价格为3562.41元，截至下午4点40分，价格已下跌至3185元，跌幅逾10%。根据该平台的历史行情数据显示，在2014年1月27日，1比特币还能兑换5032元人民币。这意味着，该平台上不到一个月，比特币价格已下跌了36.7%。

　　同年9月9日，美国电商巨头eBay宣布，该公司旗下支付处理子公司Braintree将开始接受比特币支付。该公司已与比特币交易平台Coinbase达成合作，开始接受这种相对较新的支付手段。

　　虽然eBay市场交易平台和PayPal业务还不接受比特币支付，但旅行房屋租赁社区Airbnb和租车服务Uber等Braintree客户将可开始接受这种Online casino and How to find it 。Braintree的主要业务是面向企业提供支付处理软件，该公司在2013年被eBay以大约8亿美元的价格收购。

　　On the evening of January 22, 2017, Huobi, BTC China, and OKCoin announced on their respective official websites that in order to further suppress speculation and prevent drastic price fluctuations, all platforms would start charging transaction service fees at 12:00 noon on January 24. The service fee is charged at a fixed rate of 0.2% of the transaction amount, and the fee rate for active and passive transactions is the same.

　　On May 5, the latest data from OKCoin showed that the Bitcoin price had just again set a new historical high, reaching the highest level of 9,222 yuan before the article was published. Starting at 12:00 noon on January 24, the three major Bitcoin platforms in China officially began to charge transaction fees. On September 4, the central bank and seven other ministries issued an announcement that China banned Online casino and How to find it trading. The same year on December 17, Bitcoin reached its historical highest price of 19,850 U.S. dollars.

　　On November 25, 2018, Bitcoin fell below the 4,000 U.S. dollar barrier and then stabilized at over 3,000 U.S. dollars. On November 19, the cryptocurrency market resumed its downward trend, and Bitcoin fell below the 5,000 U.S. dollar barrier for the first time since October 2017, due to the previous hard fork of BCH and the intensified review of Initial Coin Offerings (ICOs) by regulators.

　　At 4:30 a.m. on November 21, the Bitcoin price on the coinbase platform fell below 4,100 U.S. dollars, setting a new low in 13 months.

　　In April 2019, Bitcoin broke through the 5,000 U.S. dollar barrier again, setting a new high for the year. On May 12, Bitcoin broke through 7,000 U.S. dollars for the first time in nearly eight months. On May 14, according to the coinmarketcap quote, Bitcoin reached 8,000 U.S. dollars, with a 24-hour increase of 14.68%.

　　On June 22, the Bitcoin price broke through the 10,000 U.S. dollar barrier. The Bitcoin price fluctuated around 10,200, with a 24-hour increase of nearly 7%. On June 26, the Bitcoin price once again broke through 12,000 U.S. dollars, reaching a high point in nearly 17 months since January 2018. Early on June 27, the Bitcoin price approached 14,000 U.S. dollars, again setting a new high for the year.

　　On February 10, 2020, Bitcoin broke through the 10,000 U.S. dollar mark. According to trading data, the price increase of Bitcoin exceeded 3%. On March 12, according to data from the cryptocurrency trading platform Bitstamp, at 7 p.m.

　　At 44 minutes, the lowest price of Bitcoin had fallen to 5,731 U.S. dollars. On May 8, Bitcoin broke through the 10,000 U.S. dollar mark, setting a new high since February.

　　As of 7:20 p.m. on December 27, the Bitcoin price was quoted at 28,273.06 U.S. dollars.

　　2021年1月8日，比特币涨至4万美元关口上方，最高至40402美元。

　　2021年2月22日，比特币价格线上突破58000美元/枚。

　　2021年2月16日，比特币价格突破50000美元。

　　3月13日，比特币24小时上涨约6%，站上60000美元/枚，市值约为1.1万亿美元。

　　2021年5月19日，比特币跌幅扩大至18%，跌破35000美元/枚整数关口，日内连续跌破九道千元关口。

　　流通性与接受度

　　比特币仍然有合法或正当的用途。有多种途径使用比特币，通过电子货币交易所、比特币提款机、服务商和个人等渠道，就能兑换为当地的现金或金币或以现金或金币购买比特币；也可以直接使用它购买物品和服务，或使用比特币金融卡。

　　特别继维基解密宣布接受比特币捐助后，认可使用比特币的个人、组织和企业迅猛增长。

　　随着比特币金融卡的激活，即使商家不接受比特币，仍然可以依照比特币与法币的即时汇率，而以比特币付款，犹如刷人民币账户的金融卡支付外币（美元、欧元等）消费，仍然可以依照该外币与人民币的即时汇率；

　　而从人民币的存款账户扣款来完成付款，这样商家只要支持Visa或 Mastercard等信用卡或是Apple Pay等移动支付功能者皆能使用；

　　使用范围就能从直接接受比特币的1万商家，大幅扩大到包括网络购物、卖场购物、餐厅和咖啡厅用餐、搭乘交通工具、加油站加油等数千万个商家（Visa 2,900万、MasterCard 3,200万个），如果许可，并可使用世界各地逾3千多万台一般法币ATM，以比特币提领当地现金使用online casino tutorialJoin us。

　　交易

　　比特币点对点网络将所有的交易历史都存储在区块链中，比特币交易就是在区块链账本上“记账”，通常它由比特币客户端协助完成。付款方需要以自己的私钥对交易进行数字签名，证明所有权并认可该次交易。

　　比特币会被记录在收款方的地址上，交易无需收款方参与，收款方可以不在线，甚至不存在，交易的资金支付来源，也就是花费，称为“输入”，资金去向，也就是收入，称为“输出”。如有输入，输入必须大于等于输出，输入大于输出的部分即为交易手续费。

　　矿工产出交易没有输入，只有输出，交易记录会显示新生成的比特币（Newly Generated Coins），除矿工产出交易外，一个输入必然是另一笔交易的一个输出，也就是一笔收入必然是其他人的支付。

　　一个输入没有成为另一笔交易的输出时，它是“未花费的”，也就是“账户余额”。收录此交易的区块被广播后，此交易就有了“1个确认”。矿工们平均每10分钟产生一个区块，每一个新区块的诞生会使此交易的确认数加1。

　　当确认数达到6时，通常这笔交易被认为比较安全、难以逆转。比特币交易为不可逆，每一笔交易都无法撤销，商家不必遭到诈骗式的拒付而遭受损失，唯一可以获得退款的方法，就是请对方再做一笔反向交易，但需要对方的配合。

　　区块链

　　区块链（Blockchain）是比特币的一个重要概念，该概念在中本聪的白皮书中提出，区块链是一串使用密码学方法相关系产生的资料块（称为“区块”，block）。

　　新增的资料块总能链接到上一个区块，即整条区块链的尾部。比特币点对点网络将所有的交易历史都存储在“区块链”（blockchain）中，所以区块链可以看作记录着比特币交易的账本。区块链是一群分散的客户端节点，并由所有参与者组成的分布式数据库，是对所有比特币交易历史的记录。

　　中本聪预计，当资料量增大之后，用户端希望这些资料并不全部存储自己的节点中。为了实现这一目标，他采用引入散列函数机制。这样客户端将能够自动剔除掉那些自己永远用不到的部分，比方说极为早期的一些比特币交易记录。

　　中本聪创造了比特币系统的第一个区块，即“创世区块”，并附有一句“The Times 03/Jan/2009 Chancellor on brink of second bailout for banks”，而这句是当天泰晤士报的头版文章标题。

　　确认一项交易的过程，是由解决一系列计算难题的工作量证明机制来实现的。

　　工作量证明机制要求电脑的计算能力为某个有限值的情况下，需要运算一定的时间才能解决，这就使得攻击者无法重写、修改交易历史，除非他能够拥有相对比特币点对点网络系统更强大的计算能力，从而能以更快的速度产生区块链（称为”51%攻击”）。

　　工作量证明机制的难度由系统自动调节，所以新区块的生成平均需时10分钟。整个比特币点对点网络的节点都会自动检测交易和区块的有效性，并忽略任何违背规则的交易和区块，比如那些产生错误数量的区块，或多次发送同一份额比特币的交易行为。

　　参与处理区块的客户端可以得到一定量新发行的比特币，以及相关的交易手续费。

　　为了得到这些新产生的比特币，参与处理区块的用户端需要付出大量的时间和计算力（为此社会有专业挖矿机替代电脑等其他低配的网络设备），这个过程非常类似于开采矿业资源，因此中本聪将资料处理者命名为“矿工”，将资料处理活动称之为“挖矿”。

　　这些新产生出来的比特币可以报偿系统中的资料处理者，他们的计算工作为比特币点对点网络的正常运作提供保障。

　　有鉴于此，其他类似竞争币（Altcoin）都是用了相同的理念去处理端间交易资料，只是在工作量证明机制上进行调整，如采用权益证明（Proof of Stake）和Scrypt算法等

　　冷钱包通常依靠“冷设备（不联网的电脑、手机等〉确保比特币私钥的安全，运用二维码通信让私钥不触网，避免了被黑客盗取私钥的风险，但是也可能面临物理安全风险（比如电脑丢失，损坏等〉。

　　三、基本概念

　　钱包就是存储和使用lottery and How to find it 的工具，一个币对应一个钱包。用来存储币种，或者”交易币种。

　　比特币钱包使用户可以检查、存储、花费其持有的比特币，其形式多种多样，功能可繁可简，它可以是遵守比特币协议运行的各种工具，如电脑客户端、手机客户端、网站服务、专用设备，也可以只是存储著比特币私密密钥的介质，如一张纸、一段暗号、一个U盘、一个文本文档，因为只要掌握比特币的私密密钥，就可以处置其对应地址中包含的比特币。比特币无法存入一般的银行账户，交易只能在比特币网络上进行，使用前需下载客户端或接入线上网络。

　　A cold wallet refers to the Bitcoin storage technology developed by information technology companies that provide secure storage solutions for blockchain digital assets. The Kuanshen cold wallet integrates functions such as lottery and storage, multiple transaction password settings, releasing the latest market trends and information, and providing hard fork solutions, and uses QR code communication to ensure that the private key never touches the internet, effectively preventing hackers from stealing.

　　Step 1, download the imToken (version 1.003) wallet through the official channel using Huawei畅享10 (version 1.0.0). Step 2, open the APP, click ‘My’, and create a wallet at the bottom right corner: select ETH and click to create a wallet: set the wallet name and password: the wallet is created: Step 3, transfer the shib purchased from the exchange to the wallet: open the spot account of the exchange, find shib, click on withdrawal: copy and paste the copied wallet address, and click ‘Apply to Withdrawal Address’ to complete the transfer of shib to the wallet.

　　Bitcoin is a type of electronic cash similar to email, where both parties in a transaction need a ‘Bitcoin wallet’ similar to an email account and a ‘Bitcoin address’ similar to an email address. Just like sending and receiving emails, the payer sends Bitcoin directly to the recipient by computer or smartphone, according to the recipient’s address. The following table lists some websites where you can download Bitcoin wallets and addresses for free. A Bitcoin address is a string of characters about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, for example, “1GyQZPCGYMTmqY7NFhdWUrScyadRdz8WJD”. Bitcoin software can automatically generate addresses, and it does not need to be connected to the internet to exchange information when generating addresses, which can be done offline [2]. There are a very large number of available Bitcoin addresses. To put it in a vivid way, if there is an Earth in each grain of sand in the world, then the total number of Bitcoin addresses far exceeds the number of all the sands on all these ‘Earths’.

　　The Bitcoin address and private key appear in pairs, their relationship is like that of a bank card number and password. The Bitcoin address, like a bank card number, is used to record how much Bitcoin you have stored at this address. You can freely generate Bitcoin addresses to store Bitcoin. Each Bitcoin address is generated with a corresponding private key when it is created. This private key can prove that you own the Bitcoin at this address. We can simply understand the Bitcoin address as a bank card number, and the private key of this address as the password of the corresponding bank card number. You can only use the money on the bank card number when you know the bank password. Therefore, when using a Bitcoin wallet, please keep your address and private key safe.

　　After the transaction data of Bitcoin is packaged into a ‘data block’ or ‘block’ (block), the transaction is considered to be preliminarily confirmed. When the block is linked to the previous block, the transaction will receive further confirmation. After continuous confirmation by 6 consecutive blocks, this transaction is basically confirmed irreversibly. The Bitcoin peer-to-peer network stores all transaction histories in the ‘blockchain’ (blockchain). The blockchain is continuously extending, and once a new block is added to the blockchain, it will never be removed. The blockchain is actually a group of decentralized user-end nodes and a distributed database consisting of all participants, which is a record of all Bitcoin transaction histories. Satoshi Nakamoto predicted that as the data volume increases, users may not want to store all this data on their own nodes. To achieve this goal, he introduced the hash function mechanism. In this way, the user-end will be able to automatically eliminate those parts that they will never use, such as some extremely early Bitcoin transaction records. How to back up the private key of a blockchain wallet? What are the several methods?

　　When you are creating a blockchain wallet, after the creation is successful, the system will automatically generate the wallet address, public key, and private key. However, these need to be backed up by yourself, as the wallet will not help you save them. So, how should everyone back up this information? And what are the several methods?

　　Firstly, a wallet with double security, and import the private key into the Armory client (1) for cold storage (2). Users can quickly find the required private key in the client, and another advantage is that it is convenient for offline transaction transfers, without having to re-import the private key each time. At the same time, the computer’s operating system needs to be set with a password.

　　Secondly, you can create an electronic backup of the private and public keys of the wallet and synchronize them to the cloud. You can copy and paste them into a document, mark the name, and the document can be named in pinyin, and it can be garbled, but it needs to be stored in an additional document indicating the purpose of the file. However, the result of doing so may be that you forget which file the stored information is, so you need to note the information in the phone’s memo, and at the same time, you need to set up the review of the private key as a time-repeated schedule event (such as reviewing once every 2 months), and remind the phone or computer to review when the time comes. And it’s not just about recalling a few times, but you need to open the wallet that generates the private key in the backup, log in again, and see if the private key (and address) is correct.

　　???? Third, users can write down the private key, public key, and address of the wallet on documents. When naming, just make sure you can understand it. Then, save it as a jpg image format, making it look like a broken image that cannot be opened, or even better, we can compress this unopenable fake image into a zip format and disguise it as a real image. You can restore it when needed. The specific modification method can be searched on Baidu.

　　??? Fourth, the above three methods are all electronic backup methods. There is also a simple and rough method, which is to copy the private key and public key of the wallet in a notebook, making it look less deliberate and abrupt. However, everyone needs to pay attention to write clearly and neatly when copying, avoiding untidy handwriting that could lead to input errors of the private key. At the same time, the place of storage also needs to be paid attention to, which can be hidden in a private place at home (if possible, it can be stored in a bank’s safe deposit box).

　　There are four methods to back up the private key of the blockchain wallet as mentioned above. Of course, if you have a better backup method, you can also share it. You don’t have to follow the steps of the above backup methods. Finally, here is a backup suggestion: you can combine methods 2 to 4 mentioned above to back up the private key to avoid forgetting.

　　Note:

　　(1) Armory client: Armory is a fully-featured Bitcoin client that provides many innovative features that other client software does not have! Manage multiple wallets (confirmation and only viewing), print permanent paper backups, import or delete private keys, and so on.

　　(2) Cold storage: that is, the cold storage of Bitcoin wallet (Cold storage). It refers to a method of saving the wallet offline. How to create a blockchain Shiba Inu coin wallet?
