Google Play does not yet support domestic savings cards and UnionPay cards for payment. You can register using international credit cards VISA, MasterCard, or if you do not have them, these cards are available for application at Industrial and Commercial Bank of China, China Merchants Bank, and other banks.

　　Operation Environment: Windows 10 system; Google: v27.5.16-21

　　1. Binding a bank card, you need to first see what type of card you have. If it is a debit card, you can go to Google Wallet, click ‘Add Payment Method’ in the ‘Payment Methods’ tab on the left, and complete the binding according to the prompts.

　　Google Wallet, but most domestic payment methods that support foreign currencies are credit cards. If you bind in Google Wallet at this time, it will prompt ‘The product does not accept credit card payments’, thus unable to add. We must change channels and bind from ‘Play Store’ App. Open Google Play application, log in to the account. Click the menu icon in the upper left corner to open the drawer menu, click ‘Account’ – ‘Payment Method’ – ‘Add Credit or Debit Card’ and fill in the required information according to the prompts to complete the binding.

　　2. By default, the price currency should be the currency of the address you entered when adding the bank card. If you wish to receive a change, you need to modify ‘Payment Information’. This is also in the drawer menu, click ‘Account’ – ‘Payment Method’ – ‘More Payment Settings’ to open the web version of the settings, click the menu icon in the upper left corner, and select ‘Settings’.

　　Click the modify button next to ‘Country/Region’. Create new payment information according to the prompts, and then select the region corresponding to the currency you wish to use.

　　Extended Information

　　Introduction to Bank of China:

　　The full name of the Bank of China is Bank of China Limited (Bank of China Limited, abbreviated as BOC), founded on February 5, 1912, with its headquarters located at No. 1, Fuxingmen Nei Street, Beijing, and is one of the five major state-owned commercial banks. Its business scope covers commercial banking, investment banking, insurance, and aviation leasing. It has affiliated financial institutions such as Bank of China, Bank of China International, and Bank of China Insurance, providing financial services to individuals and corporate clients globally.

　　The specific operation process for binding a payment bank card in Google backend is as follows:

　　1. Log in to the backend: Select settings, drag the account details interface to the bottom, and click to set the merchant account.

　　2. The default is an individual merchant. If there is no special requirement, you can directly fill in the information on the current interface for registration. It should be noted that if the default registration (the default is an individual merchant) is used, then when binding the receiving account, only the bank card of the registered place of your Google account can be bound as the receiving account (the registration place is the default verified mobile phone number area). For example, if the mobile phone number verified during registration is Chinese, then only the bank card opened in China and the receiving amount is in US dollars can be used, and other areas or types of cards cannot be bound.

　　If there are requirements for the receiving area or you want to receive payments with the company’s card, click the name at the top, select Create payments profile, and below you can select the account type, company or individual, and also select the receiving country. It should be noted that after selecting the country, the receiving bank card must be a bank card of the current country. If you want to change the receiving area, you must create a new merchant account.

　　After completing the registration of the merchant account, return to the Google backend, select Settings, select Payment Settings, select Manage Payment Methods on the right, and select Add Payment Method.

　　When binding a bank card, carefully check the card binding requirements at the top. Taking the Hong Kong account as an example, when binding, it will prompt you that the account opening place of the receiving account must be Hong Kong, and the currency is Hong Kong dollars. After adding the information, you need to check the box to set it as the main payment method. If not checked, the payment amount will be transferred to the previously bound bank card. The new registered account defaults to the payment credit card as the main receiving card.

　　Hello! Open the sidebar in the play Store, click Account – Payment Methods – More Payment Settings. Open the ‘Payment Center’, click the menu on the left – Settings, click the edit symbol next to Country/Region, and select Create New Payment Information. If you want to pay in US dollars, select a country with US dollars as the main currency, such as the United States, and then fill in the billing address and save. After saving, click the menu, select Payment Method – Add Credit Card/Bank Card. When you buy in the play store again, the payment currency will be converted to US dollars. If you want to change it to pounds/Hong Kong dollars next time, still go to the Payment Center, switch to the corresponding region in the payment information in the menu.

　　What is Cloud Mining Chain CMC?

　　A good digital smart contract developed by the US CMC as the core technology team, based on the Ethereum smart contract as the underlying protocol, is an intelligent computing power DAPP application. Its intention is to build a blockchain ecological application system that can quantify the value scale, have certain evolutionary capabilities, and promote the construction of the blockchain ecology.

　　What does blockchain mean?

　　Blockchain (Blockchain) is an important concept of Bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a chain of data blocks generated by cryptographic methods and associated with each other. Each data block contains information about a batch of Bitcoin network transactions, which is used to verify the validity (anti-counterfeiting) of the information and generate the next block.

　　区块链，分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式。

　　注意事项：

　　1、区块链起源于比特币，2008年11月1日，一位自称中本聪(SatoshiNakamoto)的人发表了《比特币:一种点对点的电子现金系统》一文，阐述了基于P2P网络技术、加密技术、时间戳技术、区块链技术等的电子现金系统的构架理念，这标志着比特币的诞生。

　　两个月后理论步入实践，2009年1月3日第一个序号为0的创世区块诞生。几天后2009年1月9日出现序号为1的区块，并与序号为0的创世区块相连接形成了链，标志着区块链的诞生。

　　2、为了实现区块链金融大跨越大发展，为了推动中国经济新发展，加速全球资产流通，实现一代代人为之奋斗不已的复兴梦想。

　　普银集团于2016年12月9日在贵州举行普银区块链金融贵阳战略发布仪式，会上将就区块链实现资产的数字化流通、区块链金融交易模式、并对区块链服务与社会公共产业的应用落地展开探讨。币安又要“跑路”了？不要放过这匹“白天马”

　　欲戴王冠，必承其重。

　　币安作为一家创始于中国，迅速成长为全球第一的数字资产交易所，长期以来，一直承受着各路势力的“明枪暗箭”，“冷剑飞刀”。在各路写手的笔下，世界第一交易所币安，已经多次“崩溃”、“跑路”、“被抓”，“死亡次数”仅次于比特币。

　　此前针对币安的攻击“靶点”，主要集中在宕机、合规、“女员工过于漂亮”等三个方面，基本上算是有一定事实依据。然而，眼见这样一些攻击点，已经被广大吃瓜群众所“喜闻乐见”，难以起到效果，某些势力开始绞尽脑汁、“另辟蹊径”。

　　近日，一个名为卑伪31毒的账号，提出了一个惊人的观点：币安资金链疑似断裂。由于“标题党”的强大力量，引发一定关注，即便是笔者，也忍不住点开一阅。先是大跌眼镜，继而大受启发，于是有了这篇同样的标题党，希望也能多赚些点击。

　　但凡懂一点区块链的人都知道，交易所的资产储备和收入，都是可以在链上查询到的。看到上述文章，持有BNB的我，第一反应是查了一下币安冷热钱包里的数据：

　　掐指一算，币安手上至少还有价值上百亿的数字资产，断裂起来估计颇有难度。

　　再来细看文章观点，老实说，我甚至有点怀疑这是币安的“高级”广告软文：

　　1、币安理财收益太高，别人家的理财收益都只有年化2-3%，而币安的EOS理财收益“高达”年化6-8%，这么“高”的利息，币安肯定无法承兑。

　　2、币安利润太高了，明显高出行业其他交易所，同时币安每个季度拿出这么多的利润来回购BNB，明显不符合游戏规则。大家赚了钱都是股东分走的，为什么币安要这么大力度的花钱回购销毁平台币。

　　3、币安一直在扩张，不断加大区块链行业的基础投资力度，这不，刚刚花了4亿美元收购了CMC，这个太不符合逻辑。大家开交易所都是为了赚钱分钱，为什么币安要花这么多钱去发展和完善区块链生态。

　　4、新发行的USDT有79%进入了币安交易所，19%进入了火币，而某些号称头部的交易所，居然没有什么量。这个肯定是币安资金链出问题了，虚假发行USDT用来填补亏空。当然，这里有个逻辑没有搞懂的是：币安为什么可以指使竞争对手Bitfinex旗下的泰达公司，虚假发行USDT，用来填补币安的亏空。莫非币安真的是传说中的隐形“币圈盟主”，连对手都可以“号令”？

　　综上所述，卑伪31毒的主要观点是：币安太优秀了，理财收益是同行的两倍，利润是同行的几倍，回购销毁力度是同行的几倍，投资扩张力度令同行震惊，USDT的主要交易量都进了币安。如此过于优秀，那肯定是有问题的；一直这么优秀，资金链肯定会出问题。对于这样清奇的逻辑，我们一时间竟无言以对……

　　稍微缓过神之后，我们在网上陆陆续续看到一些回应：

　　首先是关于币安理财的高收益：

　　这就是币安理财高收益的秘密，币安将项目方给予的持币生息收益100%返还给了投资人，而没有收取渠道费用，“没有中间商赚差价”，从而有了所谓的“高收益”。

　　其次是币安的高利润。这个实在是没有什么好说的，作为行业当之无愧的第一交易所，无论哪个方面的数据，都实打实的摆在那里。行业利润向头部倾斜，这也是各行各业的共同现象，与苹果拿走智能手机行业70%的利润是一个道理。

　　关于BNB的高比例回购，我们可以看到，与其他同行不时推出新的公链币、矿池币不同，整个币安的生态都是围绕BNB展开的。同时，在主流交易平台中，币安的创始团队对交易所的掌控度无疑是最大。一些平台需要考虑背后股东错综复杂的利益关系，倾向于把赚到的钱快速分掉，而币安，似乎有着更高远和长久的追求。如果说行业中要选出某个交易所更富有“理想主义情怀”，更愿意把赚到的钱反哺行业，那么毫无疑问，答案是币安。

　　Lastly, regarding Binance’s significant investment moves. In the article ‘Capital Chain Breaks’, it is mentioned that Binance recently spent $400 million to acquire CMC and also invested in Tokocrypto in Indonesia. Both transactions involved CMC, the world’s largest and most authoritative blockchain data platform, and the top traffic entrance of the entire ‘crypto circle’. It can be said to be the infrastructure of the entire blockchain ecosystem, and the $4 billion valuation is truly not expensive. As for Tokocrypto, as a regulated and compliant exchange in Indonesia, although Binance has not disclosed the amount of investment and the shareholding ratio, the industry understands that any investment going in the direction of compliance is a sure thing.

　　Looking back at the past history, Binance has a relatively clear approach to the acquisition of products and projects, such as the acquisition of the Indian exchange WazirX, the options exchange JEX, and the investment in projects such as FTX and TBB. These acquisitions have all been well integrated into the Binance ecosystem and have exceeded market expectations.

　　Even for a platform that has just completed a $400 million acquisition, it is not as foolish as spending such a large sum of money in the situation of ‘the capital chain is about to break’. It is suggested that those behind the scenes should find a strong opportunity to raise the issue of the capital chain as a target of attack, preferably after Binance has not made any investment moves for several consecutive months. The title has already been thought of: ‘Binance Continues Months Without Investment, Suspected of Running Out of Capital’.

　　Unlike some peers who are eager to grab their share of the industry’s pie by various means, Binance, the industry leader, undoubtedly opts for the best choice of focusing on ‘making and expanding the pie’, constantly achieving balance and consensus with regulators in various countries while continuously expanding the boundaries of the blockchain ecosystem. Binance has indeed been doing so, facing arrows shot from behind while cutting through thorns ahead, striving to pave the way for the blockchain era.

　　Just yesterday, Binance announced the strategic merger of TravelbyBit, a flight booking platform in the Binance ecosystem that supports encrypted assets, with Travala.com, a blockchain-based accommodation booking platform. After the merger, the two companies will jointly own over 2 million hotels and 600 airlines worldwide, making them one of the largest online travel agencies globally. Both companies support payments in fiat currency and over 25 types of encrypted assets, including BTC, ETH, LTC, BNB, and BUSD.

　　The current Binance includes an ecosystem of products such as Binance Academy, Binance Charity, decentralized trading platform, global fiat currency channels, Binance Labs, issuance platform, Binance Research Institute, BinanceX, BinanceInfo, TrustWallet, DappReview, and Binance Cloud, among others. The initial form of the Binance blockchain ecosystem is already taking shape.

　　On the road to compliance, Binance is walking more and more steadily. Currently, Binance has established completely compliant fiat currency trading platforms with local partners, including Binance US fiat currency trading platform, Binance Singapore fiat currency trading platform, Binance Jersey fiat currency trading platform, Binance Uganda fiat currency trading platform, and Binance Australia fiat currency trading platform. Among them, the Binance US fiat currency trading platform has obtained MTL licenses in 37 states. On September 5, 2019, Binance jointly launched the USD-anchored stablecoin Binance BUSD with Paxos and obtained the license from the New York State Department of Financial Services (NYDFS). Globally, Binance is actively seeking in-depth cooperation with governments of various countries, such as providing legislative guidance on lottery and How to find it for the Ukrainian government.

　　In our view, what Binance aims at will never be some exchanges, but rather some ‘classical industry giants’ such as Amazon, Google, Facebook, and Goldman Sachs.

　　”What doesn’t kill you will make you stronger.” Rumors cannot defeat Binance, just as sanctions cannot defeat Huawei. We hope that one day, after the policy environment and regulatory laws are mature, the Binance originated in China can return to China openly and honestly.

　　Binance is going to ‘run away’ again, hurry up and ‘get on board’. If you’re late, this ‘day horse’ will take off into the sky. What does blockchain mean?

　　Blockchain is a new application mode of computer technology, including distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc.

　　1. Blockchain is a chain-like data structure that combines data blocks in chronological order and is guaranteed to be unalterable and unforgeable by cryptographic methods, forming a distributed ledger.

　　2. Blockchain is an important concept of Bitcoin, which is essentially a decentralized database without intermediaries. As the underlying technology of Bitcoin, it is a series of data blocks generated by cryptography and linked together.

　　Extended Information:

　　1. The Bitcoin peer-to-peer network stores all transaction histories in the ‘blockchain’. The blockchain is continuously extending, and once a new block is added to the blockchain, it will no longer be removed.

　　2. The shared value system of blockchain was first imitated by numerous cryptocurrencies, and improvements were made in terms of proof of work and algorithms, such as adopting proof of stake and SCrypt algorithm.

　　3. In fact, blockchain is a group of decentralized user-end nodes, and a distributed database composed of all participants, which records the entire transaction history of Bitcoin.

　　4. Blockchain technology will be applied to the credit investigation, transaction security, and information security in the financial industry. Blockchain can form a point-to-point digital value transfer in the financial field, thereby enhancing the security of transmission and transactions.

　　61. Being trapped

　　Expected the price of Bitcoin to rise, but unexpectedly the price fell after buying; or expected the price of Bitcoin to fall, but unexpectedly the price rose after selling.

　　62. Breaking even

　　After buying Bitcoin, the price fell, causing a temporary loss on the books, but the price later rose, turning a loss into a profit.

　　63. Missing the market

　　Sold Bitcoin after being bearish on the market, but the price kept rising all the way, failed to buy in time, and therefore failed to make a profit.

　　64. Overbought

　　The price of Bitcoin has continued to rise to a certain height, where the buying power is basically exhausted, and the price is about to fall.

　　65. Oversold

　　The price of Bitcoin has continued to fall to a certain low point, where the selling power is basically exhausted, and the price is about to rise.

　　66. Manipulating the market to make the market bullish

　　The price of Bitcoin has been consolidating for a long time, and the possibility of a decline is relatively high. Most shorts have sold Bitcoin, and suddenly the bearish side pulls up the price, luring the bulls into buying, only to be trapped by the bearish side when they push down the price.

　　67. Manipulating the market to make the market bearish

　　After buying Bitcoin, deliberately driving down the price to make shorts believe that the price will fall, causing them to sell out, and then falling into the trap set by the bulls.

　　68. What is NFT

　　NFT stands for ‘Non-Fungible Tokens’, which are simply a type of copyright proof that cannot be divided on the blockchain. Its main function is to authenticate, transfer digital assets, and is different from lottery and How to find it in that it is unique, indivisible, and essentially a unique digital asset.

　　69. What is the metaverse

　　The metaverse is a collection of virtual time and space, consisting of a series of augmented reality (AR), virtual reality (VR), and the Internet (Internet), where the functions of value transfer in this world are carried by lottery and How to find it.

　　70. What is DeFi

　　DeFi, short for Decentralized Finance, refers to ‘decentralized finance’ or ‘distributed finance’. ‘Decentralized finance’, as opposed to traditional centralized finance, refers to various applications in the financial field that are built on open decentralized networks. The goal is to establish a multi-level financial system, based on blockchain technology and cryptocurrency, to recreate and improve the existing financial system.

　　71. Who is Satoshi Nakamoto?

　　72. Bitcoin is different from QQ coin

　　Bitcoin is a decentralized digital asset without an issuing entity. QQ coin is an electronic currency issued by Tencent Company, similar to electronic points, which is not actually currency. QQ coins require a centralized issuing institution, and QQ coins can be recognized and used because of Tencent’s credit guarantee. Its usage is also limited to Tencent’s games and services, and the value of QQ coins is entirely based on people’s trust in Tencent Company.

　　比特币不通过中心化机构发行，但却能够得到全球的广泛认可，是因为比特币可以自证其信，比特币的发行和流通由全网矿工共同记账，不需要中心机构也能确保任何人都无法窜改账本。

　　73.矿机是什么？

　　以比特币为例，比特币矿机就是通过运行大量计算争夺记账权从而获得新生比特币奖励的专业设备，一般由挖矿芯片、散热片和风扇组成，只执行单一的计算程序，耗电量较大。挖矿实际是矿工之间比拼算力，拥有较多算力的矿工挖到比特币的概率更大。随着全网算力上涨，用传统的设备（CPU、GPU）挖到比特的难度越来越大，人们开发出专门用来挖矿的芯片。芯片是矿机最核心的零件。芯片运转的过程会产生大量的热，为了散热降温，比特币矿机一般配有散热片和风扇。用户在电脑上下载比特币挖矿软件，用该软件分配好每台矿机的任务，就可以开始挖矿了。每种币的算法不同，所需要的矿机也各不相同。

　　74.量化交易是什么？

　　量化交易，有时候也称自动化交易，是指以先进的数学模型替代人为的主观判断，极大地减少了投资者情绪波动的影响，避免在市场极度狂热或悲观的情况下做出非理性的投资决策。量化交易有很多种，包括跨平台搬砖、趋势交易、对冲等。跨平台搬砖是指，当不同目标平台价差达到一定金额，在价高的平台卖出，在价低的平台买入。

　　75.区块链资产场外交易

　　场外交易也叫OTC交易。用户需要自己寻找交易对手，不通过撮合成交，成交价格由交易双方协商确定，交易双方可以借助当面协商或者电话通讯等方式充分沟通。

　　76.时间戳是什么？

　　区块链通过时间戳保证每个区块依次顺序相连。时间戳使区块链上每一笔数据都具有时间标记。简单来说，时间戳证明了区块链上什么时候发生了什么事情，且任何人无法篡改。

　　77.区块链分叉是什么？

　　在中心化系统中升级软件十分简单，在应用商店点击“升级”即可。但是在区块链等去中心化系统中，“升级”并不是那么简单，甚至可能一言不合造成区块链分叉。简单说，分叉是指区块链在进行“升级”时发生了意见分歧，从而导致区块链分叉。因为没有中心化机构，比特币等数字资产每次代码升级都需要获得比特币社区的一致认可，如果比特币社区无法达成一致，区块链很可能形成分叉。

　　78.软分叉和硬分叉

　　硬分叉，是指当比特币代码发生改变后，旧节点拒绝接受由新节点创造的区块。不符合原规则的区块将被忽略，矿工会按照原规则，在他们最后验证的区块之后创建新的区块。软分叉是指旧的节点并不会意识到比特币代码发生改变，并继续接受由新节点创造的区块。矿工们可能会在他们完全没有理解，或者验证过的区块上进行工作。软分叉和硬分叉都”向后兼容”，这样才能保证新节点可以从头验证区块链。向后兼容是指新软件接受由旧软件所产生的数据或者代码，比如说Windows10可以运行WindowsXP的应用。而软分叉还可以”向前兼容”。

　　79.区块链项目分类和应用

　　从目前主流的区块链项目来看，区块链项目主要为四类：第一类：币类；第二类：平台类；第三类：应用类；第四类：资产代币化。

　　80.对标美元的USDT

　　USDT是Tether公司推出的对标美元（USD）的代币TetherUSD。1USDT=1美元，用户可以随时使用USDT与USD进行1:1兑换。Tether公司执行1:1准备金保证制度，即每个USDT代币，都会有1美元的准备金保障，对USDT价格的恒定形成支撑。某个数字资产单价是多少USDT，也就相当于是它的单价是多少美元（USD）。

　　81.山寨币和竞争币

　　山寨币是指以比特币代码为模板，对其底层技术区块链进行了一些修改的区块链资产，其中有技术性创新或改进的又称为竞争币。因为比特币代码开源，导致比特币的抄袭成本很低，甚至只需复制比特币的代码，修改一些参数，便可以生成一条全新的区块链。

　　Big data is the means of production, AI is the new productive force, and blockchain is the new productive relations. Big data refers to a set of data that cannot be captured, managed, and processed by conventional software tools within a certain time range, and it is a massive, high-growth, and diverse information asset that requires a new processing mode to have stronger decision-making power, insight discovery power, and process optimization capabilities. Simply put, big data is a long-term accumulated massive amount of data that cannot be obtained in the short term. Blockchain can be used as a way to obtain big data, but it cannot replace big data. Big data is just a medium for running on the blockchain, without absolute technical performance, so the two cannot be confused. (The simple understanding of productive relations is the labor exchange and consumption relationship, the core of which lies in the productive force, and the core of productive force lies in the production tools)

　　ICO, Initial Coin Offering, is the crowdfunding in the blockchain lottery and How to find it industry.

　　Google tax refers to the 30% cut Google takes from the payments made through the Google Play Store. Developers who publish Android applications on the Google Play Store must use Google’s payment system and can no longer use independent payment systems; their in-app purchase income will be subject to a 30% cut by Google.

　　Google uses the real-time exchange rate at the time of payment. Google will use the exchange rate at the time the buyer places an order, converting the sales proceeds in the buyer’s currency into the corresponding proceeds in the currency used by Google’s account. This exchange rate is updated around the clock, so the system will perform conversion each time the order proceeds are collected, and you will see the corresponding exchange rate in the order receipt of each application.

　　Google’s settlement cycle is the natural month, but it uses PST (time difference of 16 hours) / PDT (time difference of 15 hours), and the settlement and payment time is generally the latter part of the following month.
