③ 小白实操 I 主流数字货币钱包，哪个好用

小白的话，建议先使用轻钱包，比如极客钱包、imtoken、cobo等，操作简单比较容易上手。如果金额比较大，建议使用冷钱包，不过操作相对复杂一些

④ 冷钱包和助记词是哪里生产的

产地瑞士。冷钱包则是离线钱包，网络不能访问到你存储私钥的位置，它是非联网的钱包。冷钱包则是依靠“冷”设备确保数字货币私钥的安全，在非联网的情况下，通过电脑、手机、写着私钥地址的小本本。例如.Ledger钱包：比特币硬件钱包制造商Ledger是数字货币安全领域技术领先的公司之一，能为消费者和企业提供值得信赖的硬件。Ledger是基于智能卡的比特币硬件钱包，提供技术领先的最高保护等级，兼具可用及操控性。
Ledger硬件钱包是一个多功能钱包，安全存储私钥的硬件设备，查看钱包和发送交易时，硬件钱包需要与软件钱包配合才能使用。同时支持安全存储比特币、以太坊及平台代币、Zcash等。其项目已经在Github上开源。基于其硬件设备，你既可以使用Ledger开发的软件钱包，也可以使用其他团队开发的软件钱包，即可以配合以太坊网页钱包MyEtherWallet或者Parity钱包使用Ledger。
拓展资料：
一、热钱包和冷钱包的优缺点：
1、从安全方面考虑，相较而言，比特币冷钱包被黑客攻击的可能性更低，这也是为什么不少监管机构要求交易平台通过离线方式保存用户加密资产的原因。冷钱包由于不能被网络访问，避免了黑客盗取私钥的风险，只要保存得当，相比热钱包会更安全。
但如果从便捷方面考虑，联网状态下的热钱包可以随时进行资产交易，使用体验更加方便快捷。因此对于资产较大的持有者来说，冷热钱包一起使用可以在便捷操作的同时隔离风险，更好的保障虚拟货币资产安全。
2、冷钱包和热钱包都通过钱包地址来实现数字资产的交易。如何理解钱包地址呢？我们可以把它想象成你去银行开户，银行给你卡号，别人就可以通过这个卡号给你转账。一般来说，钱包地址和私钥是成对出现的，钱包地址就是你的银行卡号码，对应私钥就像你的银行卡号的密码。钱包地址记录你在该钱包地址上存有多少币，你只有在知道密码的情况下才能有资格去使用银行卡号上的钱。
3、私钥和钱包地址一样是数字资产交易中的关键要素，无论你是使用冷钱包还是热钱包储存数字资产，只要任何人知道了你的钱包私钥，就能随意转走并处置你的数字资产。总之，谁手握私钥，谁才是加密数字钱包真正的主人。因此，在使用钱包时请务必保存好它们。

⑤ 冷钱包和轻钱包有什么区别

冷钱包它也有人叫做离线钱包，也就是没有联网的环境下使用的钱包。例如说将私钥或者助记词写在纸上、专业的硬件钱包、还有人利用不联网的设备制作冷钱包。我们使用冷钱包的优点在于安全，缺点是交易、创建钱包都麻烦。轻钱包（SPV）SPV指的是“支付验证”而不是“交易验证”。轻钱包是用瘦客户端模式实现的钱包，它不
储存完整的区块链，只保存和自已相关的数据。所以，它的体积小，可以在手机、电脑、网
页等运行。轻钱包的优点在于：1、不占用内存，2、是支持多种数字资产，3、用户体验好，新手上手快。缺点在于交易验证会慢。

⑦ 有人知道虚拟货币中冷钱包和热钱包的区别吗

冷钱包意味着没有联网的电脑或者真实钱包，反过来就是热钱包，两者的区别在于是否联网。也就是安全性的问题。

⑧ 新手如何炒虚拟货币

一、估算前景，收集意见
香港两位90后虚拟货币投资者——马光健(KK)及刘胜钧(Harvey)表示，他们注意到内地每次出招严打，比特币价格虽然出现暴跌，但很快就出现反弹拉升，证明具升值潜力。不过，包括罗杰斯、摩根大通总裁戴蒙等很多投资大师及银行间们不时抨击比特币等虚拟货币，认为这是一种骗局，没有任何投资价值。然而，业内人士认为，这是因为这些银行家“害怕”比特币，比特币底层技术未来将对传统金融机构造成重大冲击。
二、开立电子钱包储存
如果投资者觉得投资比特币可靠，那么可通过不同的方式投资比特币，但应该在购买之前开立电子钱包，以存放来自不同途径的比特币或套现。
钱包下载后，用户会获个人账户编号或专属QR CODE，在进行买卖交易时用。钱包分热钱包及冷钱包，热钱包为在线钱包，用法较方便，可在手机或电脑上免费下载，其中以Blockchain Wallet最多用家选用，已录逾1亿个交易，但遭黑客入侵概率较大，建议存放金额较细交易。冷钱包是一个实物硬件储存装置，近似网上银行“保安编码器”及USB，其中Trezor及Ledger Nano较受欢迎，冷钱包提存货币时要携带硬件在身，但安全性更高，适合存放金额较高交易。
三、选择不同的交易方式
1. 比特币ATM简单快捷;不需要预先作账户登记，并会以匿名交易，买家直接投入纸币后，便可在ATM机扫描个人比特币钱包内的QR CODE进行交易，部分ATM机也能打印出私密金钥，买家可自行将成功购入的比特币存入“钱包”，这为最简单快捷的方法，同时未有限定入场费，只要是纸币便可。
2.面对面就近交易:类似产品拍卖平台般，Localbitcoins会以买家所在地定位，寻找位处邻近地区卖家，买卖双方可直接沟通议价，并自行定下交收方法。这种交易方式可一手交现金，一手交比特币”。
3.交易所交易:市场上有多家来自世界各地的比特币交易所，交易额较大的交易所包括，火币、币安、OKEX、Bitfinex，Bitstamp，Gemini及Gatecoin。近日每个比特币价格近4，000美元，但投资者也可选择只购买0.1个比特币。付款方法通常选电汇，申请账户程序较繁琐。手续费则根据各交易所而定，以Gatecoin为例，手续费由0.02%至0.35%不等。
四、准备文件，申请开户
透过交易所买入比特币前，买家需在交易所网站申请个人账户，递交个人资料，包括准备以下文件，成功上传所有文件后，一般需等待数天便会收到确认邮件。文件包括身份证明文件(护照/身份证)、3个月内住址证明(水电煤账单)、银行户口资料、手机号码，以及手持身份证明文件所拍的个人照。
五、风险极大，不容忽视
虽然虚拟货币看似好炒，但因它属一种另类投资，涉及风险相当高，价格波幅大，一日之间可随时暴跌数百美金，在多个国家仍被视为非法货币，对投资者保障不足。另外，交易所亦有可能被黑客入侵，其中一所交易所Bitfinex去年曾遭黑客入侵，令到大约6500万美元的比特币被盗，投资者资金变相化为乌有。

⑨ 如何使用ledger nano s 钱包

要看个人对屏幕需求，我喜欢SE，单手操作方便，绝对不是噱头，就是好用。6出来时间有点长了，电子产品更新换代快，买新不买旧。

⑩ 冷钱包和助记词硬件是怎么做的

通过可信任的助记词、增加灵活性。
软件冷钱包，不同于硬件冷钱包，软件冷钱包使用纯软件的方式实现冷钱包功能。用户需要使用两部手机，其中一部永久离线，作为冷钱包存储私钥（助记词）。另一部联网，作为观察钱包使用。软件冷钱包和硬件冷钱包实现同样的功能，安全级别类似。但是它们有一些显著的区别：软件冷钱包可以使用闲置手机，没有额外的硬件；硬件冷钱包通过数据线或蓝牙传输数据，而软件冷钱包通过扫描二维码。
可信任的助记词：软件冷钱包可以实现更彻底的去信任（即不需要信任软件开发者），用户可以自行证明其钱包的绝对安全性。在资产安全中，首当其冲的是助记词的安全。而在助记词的安全中，首要确认是助记词生成的随机性。如果您使用了一个作恶的硬件厂商（或者有 bug）的硬件钱包，您可能在第一步就已经陷落了。
在使用软件冷钱包时，你可选择信任软件，让其帮助您生成助记词。也可以选择不信任软件，自行在它处生成助记词。因此，软件冷钱包的助记词的安全性高于硬件冷钱包。
软件冷钱包比硬件冷钱包更加灵活。通常软件冷钱包可以实现比硬件冷钱包更加复杂的功能。软件冷钱包的灵活性，也让其在资产的恢复方面也更加有优势。如果您的硬件钱包损坏，需要购买（同一厂商）的硬件，进行硬件恢复。而使用软件冷钱包，则没有这样的顾虑。
拓展资料：
目前市场上，虽然主要的冷钱包产品依然是以硬件冷钱包为主，但是它们正在受到软件冷钱包的冲击。硬件冷钱包： Ledger 是最知名的硬件冷钱包方案提供商； Trezor 是另一个知名的硬件冷钱包提供商；软件冷钱包：Ownbit 是最早实现软件冷钱包方案的钱包，也是支持冷钱包币种最多的钱包之一； Parity Signer 是 Parity 出品的以太坊软件冷钱包；未来事物发展的方向永远是化繁为简。越来越多的冷钱包正在以软件的方式实现。

For beginners, it is recommended to use light wallets first, such as geek wallet, imtoken, cobo, etc., which are simple and easy to operate Get started. If the amount is relatively large, it is recommended to use a cold wallet, but the operation is relatively complicated

④ Where are the cold wallet and mnemonic words produced?

Origin: Switzerland. A cold wallet is an offline wallet. The network cannot access the location where you store your private keys. It is a non-networked wallet. Cold wallets rely on "cold" equipment to ensure the security of digital currency private keys. When not connected to the Internet, they use computers, mobile phones, and small notebooks with private key addresses written on them. For example. Ledger Wallet: Bitcoin hardware wallet manufacturer Ledger is in the field of digital currency securityOne of the leading technology companies providing trusted hardware to consumers and businesses. Ledger is a smart card-based Bitcoin hardware wallet that provides the highest level of technological leadership and is both usable and controllable.
Ledger hardware wallet is a multi-functional wallet, a hardware device that securely stores private keys.

Extended information:
1. Advantages and disadvantages of hot wallets and cold wallets:
1. From a security perspective, in comparison, Bitcoin cold wallets are less likely to be hacked. This is also The reason why many regulatory agencies require trading platforms to store users’ crypto assets offline. Since cold wallets cannot be accessed by the network, they avoid the risk of hackers stealing private keys. As long as they are properly stored, they will be safer than hot wallets.
But if we consider convenience, hot wallets under the Internet can conduct asset transactions at any time, making the user experience more convenient and faster. Therefore, for holders with larger assets, using hot and cold wallets together can isolate risks while facilitating operations, and better ensure the security of virtual currency assets.
2. Both cold wallets and hot wallets use wallet addresses to realize digital asset transactions. How to understand the wallet address? We can think of it like you go to a bank to open an account, the bank gives you a card number, and others can transfer money to you through this card number. Generally speaking, the wallet address and the private key appear in pairs. The wallet address is your bank card number, and the corresponding private key is like the password of your bank card number. The wallet address records how many coins you have in that wallet address. You can only use the money on your bank card number if you know the password.
3. The private key, like the wallet address, is a key element in digital asset transactions. Whether you use a cold wallet or a hot wallet to store digital assets, as long as anyone knows your wallet private key, they can transfer it and transfer it at will. Dispose of your digital assets. In short, whoever holds the private key is the real owner of the encrypted digital wallet. So be sure to save them when using your wallet.

⑤ What is the difference between a cold wallet and a light wallet?

Cold wallets are also called offline wallets, which are wallets used in an environment without an Internet connection. For example, private keys or mnemonics are written on paper, professional hardware wallets, and some people use devices that are not connected to the Internet to create cold wallets. The advantage of using cold wallets is security, but the disadvantage is that transactions and wallet creation are troublesome. Light wallet (SPV) SPV refers to "payment verification" rather than "transaction verification". A light wallet is a wallet implemented in thin client mode. It does not
Store the complete blockchain and only save data related to itself. Therefore, it is small in size and can be run on mobile phones, computers, web pages, etc. The advantages of light wallets are: 1. It does not occupy memory, 2. It supports a variety of digital assets, 3. The user experience is good and newbies can get started quickly. The disadvantage is that transaction verification will be slow.

⑥ How to use cold wallets

⑦ Does anyone know the difference between cold wallets and hot wallets in virtual currencies

A cold wallet means a computer or a real wallet without an Internet connection, and the opposite is a hot wallet. The difference between the two is whether it is connected to the Internet. That is the issue of security.

⑧ How to speculate in virtual currencies for beginners

1. Estimating prospects and collecting opinions
Two post-90s virtual currency investors in Hong Kong - Ma Guangjian (KK) and Liu Shengjun (Harvey) They said that they noticed that every time the mainland launched a severe crackdown, although the price of Bitcoin plummeted, it soon rebounded and increased, proving that it has the potential to appreciate. However, many investment gurus and banks, including Rogers and JPMorgan Chase CEO Dimon, have criticized Bitcoin and other virtual currencies from time to time, believing that they are a scam and have no investment value. However, industry insiders believe that this is because these bankers are "afraid" of Bitcoin, and the underlying technology of Bitcoin will have a major impact on traditional financial institutions in the future.
2. Open an electronic wallet for storage
If investors feel that investing in Bitcoin is reliable, they can invest in Bitcoin in different ways, but they should open an electronic wallet before purchasing to store Bitcoins from different channels. Or cash out.
After downloading the wallet, the user will receive a personal account number or exclusive QR CODE, which can be used when conducting buying and selling transactions. Wallets are divided into hot wallets and cold wallets. Hot wallets are online wallets that are more convenient to use and can be downloaded for free on mobile phones or computers. Among them, Blockchain Wallet is the most popular one and has recorded more than 100 million transactions. However, the probability of being hacked is relatively high. Large, it is recommended to deposit transactions with smaller amounts. A cold wallet is a physical hardware storage device, similar to an online banking "security code" and USB. Among them, Trezor and Ledger Nano are the most popular. Cold wallets require you to carry the hardware with you when withdrawing and depositing currency, but they are more secure and are suitable for storing larger amounts. High transaction.
3. Choose different transaction methods
1. Bitcoin ATM is simple and fast; no account registration is required in advance, and transactions will be anonymous. Buyers can scan their personal Bitcoins at the ATM machine after directly inserting banknotes. Use the QR CODE in the wallet to conduct transactions, and some ATM machines can also print out private keys. Buyers can deposit the successfully purchased Bitcoins into the "wallet" by themselves. This is the simplest and fastest method, and there is no restriction on admission. The fee is fine as long as it is banknotes.
2. Face-to-face and nearby transactions: Similar to a product auction platform, Localbitcoins will locate the buyer’s location and find nearby places.District sellers, buyers and sellers can directly communicate and negotiate prices, and set their own settlement methods. This transaction method allows you to pay cash in one hand and Bitcoin in the other hand."
3. Exchange trading: There are many Bitcoin exchanges from all over the world on the market. Exchanges with large transaction volumes include Huobi, Binance, OKEX, Bitfinex, Bitstamp, Gemini and Gatecoin. Recently, the price of each Bitcoin is nearly 4,000 US dollars, but investors can also choose to purchase only 0.1 Bitcoin. The payment method is usually wire transfer, and the account application process is more cumbersome. The handling fee depends on each exchange. Taking Gatecoin as an example, the handling fee ranges from 0.02% to 0.35%.
4. Prepare documents and apply for account opening
Before buying Bitcoin through the exchange, buy Home users need to apply for a personal account on the exchange website and submit personal information, including preparing the following documents. After successfully uploading all documents, it usually takes a few days to receive a confirmation email. Documents include identity documents (passport/ID card), 3 Proof of address within one month (water, electricity and gas bills), bank account information, mobile phone number, and personal photo taken with identity document.
5. The risk is extremely high and cannot be ignored
Although virtual currencies seem easy to speculate , but because it is an alternative investment, the risks involved are quite high, and the price fluctuates greatly. It can plummet by hundreds of dollars at any time in a day. It is still regarded as illegal currency in many countries, and there is insufficient protection for investors. In addition, trading Exchanges may also be hacked. One of the exchanges, Bitfinex, was hacked last year, resulting in approximately US$65 million in Bitcoins being stolen, and investor funds disappearing in disguise.

⑨ How to use ledger nano s wallet

It depends on personal needs for the screen. I like the SE. It is easy to operate with one hand. It is definitely not a gimmick, but it is easy to use. The 6 has been out for a long time, and electronic products are updated quickly. Buy a new one. Don’t buy old ones.

⑩ How cold wallets and mnemonic hardware are made

Increase flexibility through trusted mnemonics.
Software cold wallets are different Compared with hardware cold wallets, software cold wallets use pure software to implement cold wallet functions. Users need to use two mobile phones, one of which is permanently offline as a cold wallet to store private keys (mnemonic phrases). The other is connected to the Internet for observation Wallet use. Software cold wallets and hardware cold wallets implement the same functions and have similar security levels. But they have some significant differences: software cold wallets can use idle mobile phones with no additional hardware; hardware cold wallets transmit data through data cables or Bluetooth , while the software cold wallet scans the QR code.
Trusted mnemonic: The software cold wallet can achieve more complete trustlessness (that is, there is no need to trust the software developer), and users can prove the absolute security of their wallets by themselves Safety. In asset security, the first thing that bears the brunt is the security of the mnemonic phrase. In the security of the mnemonic phrase, the first confirmation is the randomness of the mnemonic phrase generation. If you use a malicious hardware manufacturer (orWith buggy hardware wallets, you might be stuck at the first step.
When using a software cold wallet, you can choose to trust the software and let it help you generate a mnemonic phrase. You can also choose not to trust the software and generate the mnemonic phrase yourself elsewhere. Therefore, the security of the mnemonic phrase of software cold wallet is higher than that of hardware cold wallet.
Software cold wallets are more flexible than hardware cold wallets. Generally, software cold wallets can implement more complex functions than hardware cold wallets. The flexibility of software cold wallet also makes it more advantageous in asset recovery. If your hardware wallet is damaged, you need to purchase hardware (from the same manufacturer) for hardware recovery. With software cold wallets, there are no such concerns.
Extended information:
At present, although the main cold wallet products in the market are still hardware cold wallets, they are being impacted by software cold wallets. Hardware cold wallet: Ledger is the most well-known hardware cold wallet solution provider; Trezor is another well-known hardware cold wallet provider; Software cold wallet: Ownbit is the first wallet to implement software cold wallet solution and supports the most cold wallet currencies One of the wallets; Parity Signer is an Ethereum software cold wallet produced by Parity; The direction of future development of things is always to simplify the complex. More and more cold wallets are being implemented in software.
