钱包就是地址，钱包分三种：
1. 交易所的钱包（热钱包）
2. App安装的钱包（热钱包）
3. 硬件生成的钱包（冷热钱包）

解答：
- 热钱包：私钥掌握在你和他之间。
- 冷钱包：私钥掌握在你手上，但是……

为什么这里我说硬件钱包是冷热钱包呢？
原因很简单，你申请到的硬件密钥，在交易时需要连接网络才能交易。在我的学识里，只要连接网络的东西一律是热钱包，除非你不交易。你怎么知道这东西上线使用时密钥是否已发送到对方服务器？鬼知道！所以我才建立币铺子自己查。

------------------------------------------------------------------------

真正的冷钱包是自己生成的，在自己电脑离线生成的字符串密钥。只要这字符密钥串不丢失，你的钱包地址永远是那条钱包地址。

自己怎么生成呢？
有技术的可以使用JS和网页文件生成。
如果不会生成怎么办？使用ChatGPT给到你JS文件和HTML页面代码即可，直接在自己的浏览器运行HTML页面即可获得随机地址和密钥。
得到的密钥你可以输入到一个手机离线钱包App里面，看看是否和生成出来的钱包地址一样。如果一样，那么就是冷钱包了。
为了安全，你测试后删除钱包并重新下载，这样更安全！

接下来，你会想怎么看余额交易记录？这不就有了币铺子在线查询！只要输入钱包地址，就能查询到钱包信息。反正不交易就当冷钱包观察钱包使用查询。

如果你要使用钱包交易，那么就一定变成热钱包，所以冷钱包的意义就是观察钱包，这下你应该知道安全意思怎么去处理了吧。

A wallet is an address, and there are three types of wallets: 1. exchange wallets (hot wallets) 2. App-installed wallets (hot wallets) 3. hardware-generated wallets (hot and cold wallets) Solution: - Hot wallet: the private key is held between you and him. - Cold wallet: the private key is in your hands, but ...... Why do I say here that hardware wallets are hot and cold wallets? The reason is simple, you apply for the hardware key and you need to be connected to the network in order to trade. In my school of thought, anything that is connected to the internet is always a hot wallet, unless you don't trade it. How do you know if the key has been sent to the other side's server when the thing is online and in use? How the hell do you know? That's why I set up a coin store to find out for myself. A real cold wallet is a self-generated string of keys that you generate offline on your own computer. As long as that character key string is not lost, your wallet address will always be that wallet address.
