2. 国内如何买到以太坊

很多平台都可以买，不翻 墙的话推荐Ebit

3. 如何购买以太坊，以太坊国内如何购买

目前，国内用户购买以太坊的渠道有很多，下面简单介绍常用的几种：

一、场外可盈可乐平台（CoinCola）

1、关于可盈可乐

可盈可乐是个人与个人之间交易比特币的场外交易平台。

顶栏进度条显示已收货，说明数字币已到钱包，根据卖家的行为进行评论，点击提交，完成交易。

二、交易平台C2C交易

关于交易平台的C2C交易，随着交易平台的数量剧增和竞争压力，很多交易平台都会有自己的C2C交易，这里我们以比较大的ZB交易平台为例给大家进行说明；

1、C2C是什么？

C2C交易就是客户对客户的交易，由交易平台提供担保。这样的平台有很多，比如：火币、otcbtc、比特派OTC等，都是由平台提供担保，用户之间进行交易的模式。我们可以简单理解为：我们在淘宝网购物的情形，和那一样。如有纠纷，平台进行仲裁。只要按照正常的流程进行交易，交易的安全性能得到保障。

2、ZB的C2C业务

ZB平台通过法币可以购买的选择有两个：QC和USDT，基本的逻辑是一样的，USDT很多平台都有，QC目前是ZB、EXX等几个平台的特色，这里重点介绍QC。

关于QC

QC是一种代币，目前市面上大家可能相对了解多一些的是USDT和BITCNY。ZB上面目前有QC交易的专区，简单来说就是可以用QC买到ZB上面的所有其他数字货币(BTC、ETH、EOS等)，所以，用RMB充值购买QC后，就可以在ZB站内进行币币交易。

QC代币的优势：

和人民币的兑换比例1:1，比较易于换算。

用QC购买其他代币，可以直观的理解为人民币购买，对货币价格有直观的了解。

到账速度快，正常半个小时左右。拥堵时2个小时左右到账。

ZB平台相对可靠，ZB的信誉度从过往来看还是很不错。

3、ZB的C2C如何操作？

登录ZB交易平台 ，点击页面上放的 “C2C交易”。

到达QC交易页面，需要首先绑定一张你的银行卡。然后，在买入QC的界面，输入你想要购买的QC数量。目前QC和人民币的比例是1:1。输入买入数量后点击「立即买入」。

点击“立即买入”后，会提示你30分钟内完成付款。同时生成付款信息。请注意，务必按照提示的要求打款。

官方说法：

商家处理时间9:00 - 21:00。非处理时间的订单会在第二天9:00开始处理，一般接单后24小时内会完成打款。

这里指的是你打款过去的商家会在24小时内将QC币转至你的账户。根据我的经验，白天一般2个小时之内就可以到账。

务必需要重点注意的几点：

1) 务必使用刚刚绑定的银行卡转账打款。

2) 备注信息(那个6位数字)一定要填写

3) 务必不要使用支付宝、微信等转账。

4) 对方账号不要填写错误。

1-2小时左右，可以在财务中心查询你的QC是否到账。

到账后，就可以在“现货交易”里面的“QC”专区进行交易了。可以选择你想要买入的交易对挂单买入。

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。

6. 以太坊钱包地址在哪里 如何买卖以太坊

以太坊钱包地址就是你的银行卡号，倘若你把地址忘了，可以用私钥、助记词、keystore+密码，导入钱包找回。买卖以太坊就更简单了，你在领域王国用100美元就能开户，然后对价格进行分析买涨买跌，买对方向就说明是盈利了。

7. 以太坊在哪里购买比较稳妥

目前数字货币钱包有很多，个人体验不错的大概有以下几款。

轻钱包不错的有：imtoken、极客钱包(geekwallet)、kcash、cobo等

硬件钱包不错的有：ledger、Trezor等，涉及数字货币金额比较大或者长期持有的，一般推荐使用硬件钱包

大体介绍一下这几款个人认为不错的轻钱包。

1、imToken：

不足：1.钱包的“发现”模块不够直观。2.只能存放在以太坊平台上开发的代币，像BTC ,NEO 这种自有公链的代币就不能存放，同时那些比特币的分叉币，更不能存放了。

2、极客钱包（geekwallet）

极客钱包是一款简单便捷的轻钱包，支持比特币（BTC）、莱特币（LTC）、以太坊（ETH）、EOS、USDT等主流数字货币资产的存储与管理。采用BIP44助记词、本地私钥、离线签名等安全机制，以及手机、电脑双备份策略，彻底解决被黑客攻击、感染病毒、手机丢失、遗忘助记词等各种方式导致的数字货币资产丢失，为用户提供线上多链数字资产一站式管理服务。平台还有跳骚市场，可以进行实物资产上链的代币买卖。

优点：安全系数高，采用本地私钥安全机制，以及手机、电脑双备份策略，支持目前主流的币种，平台有一个跳骚市场，可以进行实物资产上链的代币买卖。

不足：USDT交易必须要用0.0001个BTC作为交易手续费，不支持一些小币种，页面优化不错，但功能比较少。

3、kcash

Kcash同样是一款轻钱包，目前支持BTC、ETH、LTC、ETC、ACT和基于以太坊及Achain智能合约平台的数字货币。Kcash拥有跨链和跨合约技术，支持的币种目前还在持续增加中。

优点：Kcash作为多链钱包，支持多类数字货币，对于投资多个系列数字货币的用户非常友好。此外，Kcash还有发红包功能，未来更会推出币币交易、连接银行卡等功能。

8. 关于以太坊不同平台的钱包地址的问题

要看地址是符合哪种规范的。
最好是有自己的钱包，有的钱包可以管理不同的币。
概念上代币什么的要搞清。要看懂英文。

2. C2C transactions on trading platforms

Regarding C2C transactions on trading platforms, with the rapid increase in the number of trading platforms and competitive pressure, many trading platforms will have their own C2C transactions. Here we compare The large ZB trading platform will be taken as an example to illustrate;

1. What is C2C?

C2C transactions are customer-to-customer transactions, guaranteed by the trading platform. There are many such platforms, such as Huobi, otcbtc, Bitpie OTC, etc., all of which are guaranteed by the platform and are used for transactions between users. We can simply understand it as: the situation when we shop on Taobao is the same as that. If there is a dispute, the platform will arbitrate. As long as the transaction is conducted according to normal procedures, the security of the transaction is guaranteed.

2. ZB’s C2C business

The ZB platform has two options for purchasing through legal currency: QC and USDT. The basic logic is the same, and there are many USDT platforms. Yes, QC is currently a feature of several platforms such as ZB and EXX. Here we focus on QC.

About QC

QC is a kind of token. Currently, the ones on the market that everyone may know more about are USDT and BITCNY. ZB currently has a special area for QC transactions. Simply put, you can use QC to buy all other digital currencies on ZB (BTC, ETH, EOS, etc.). Therefore, after using RMB to recharge to buy QC, you can trade on the ZB site. Coin trading.

Advantages of QC tokens:

The exchange ratio with RMB is 1:1, making it easier to convert.

Using QC to purchase other tokens can be intuitively understood as purchasing in RMB, giving you an intuitive understanding of currency prices.

The payment is received quickly, usually about half an hour. It takes about 2 hours to arrive due to congestion.

The ZB platform is relatively reliable, and ZB’s credibility has been very good in the past.

3. How to operate ZB’s C2C?

To reach the QC transaction page, you need to bind your bank card first. Then, on the QC buying interface, enter the quantity of QC you want to buy. The current ratio of QC to RMB is 1:1. After entering the purchase amount, click "Buy Now".

After clicking "Buy Now", you will be prompted to complete the payment within 30 minutes. Payment information is also generated. Please note that you must pay according to the prompts.

Official statement:

Merchant processing time is 9:00 - 21:00. Orders placed outside processing hours will be processed starting at 9:00 the next day, and payment will generally be completed within 24 hours after receiving the order.

What this means is that the merchant you pay to will transfer QC coins to your account within 24 hours. According to my experience, the account can usually be received within 2 hours during the day.

Some important points that need to be paid attention to:

1) Be sure to use the bank card you just bound to transfer money.

2) The remark information (the 6-digit number) must be filled in

About 1-2 hours, you canPlease contact the Service Center to check whether your QC has arrived.

After receiving the money, you can trade in the "QC" area in "Spot Trading". You can select the trading pair you want to buy and place a purchase order.

4. Where are cold wallets and mnemonics 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 one of the technology leaders in the field of digital currency security, providing consumers and businesses with trustworthy hardware. 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. When viewing the wallet and sending transactions, the hardware wallet needs to be used in conjunction with the software wallet. It also supports safe storage of Bitcoin, Ethereum and platform tokens, Zcash, etc. Its project has been open sourced on Github. Based on its hardware equipment, you can use either the software wallet developed by Ledger or the software wallet developed by other teams. That is, you can use Ledger with the Ethereum web wallet MyEtherWallet or Parity wallet.
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, who hands it?Who is the real owner of the encrypted digital wallet if you hold the private key? So be sure to save them when using your wallet.

5. How the cold wallet and mnemonic hardware are made

Increase flexibility through trusted mnemonic words.
Software cold wallet is different from hardware cold wallet. Software cold wallet uses pure software to realize the cold wallet function. 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 one is connected to the Internet and used as an observation wallet. 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 via data cable or Bluetooth, while software cold wallets scan QR codes.
Trusted mnemonic: 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. In asset security, the first thing that bears the brunt is the security of mnemonic phrases. In the security of mnemonic words, the first confirmation is the randomness of mnemonic word generation. If you use a hardware wallet from a rogue hardware manufacturer (or a buggy one), you may already be trapped on 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.

6. Where is the Ethereum wallet address and how to buy and sell Ethereum

The Ethereum wallet address is your bank card number. If you forget the address, you can Use the private key, mnemonic phrase, keystore+password and import it into the wallet to retrieve it. Buying and selling Ethereum is even simpler. You can open an account in Realm Kingdom with $100, and then analyze the price to buy up or down., buying in the right direction means making a profit.

7. Where is it safer to buy Ethereum?

There are many digital currency wallets at present, and the ones with good personal experience are probably the following ones.

Good light wallets include: imtoken, geekwallet, kcash, cobo, etc.

Good hardware wallets include: ledger, Trezor, etc., involving digital currency amounts For larger wallets or long-term holdings, it is generally recommended to use hardware wallets
