　　Note:

　　An unconnected mobile phone is a cold wallet, while a mobile phone with private key information connected to the internet is an observation wallet. An observation wallet without private key information can transfer funds when the offline signature of the cold wallet is available. If there is no offline signature of the cold wallet, the observation wallet cannot transfer funds.

　　Most cryptocurrencies are decentralized and have no support from central banks or governments. In the world of blockchain, whoever holds the private key represents that person owning the corresponding asset ownership of that private key.

　　This also means that when the private key of your Bitcoin or EOS and other currencies is stolen, you cannot do as with the traditional bank savings card or credit card being stolen, where the bank can refund the lost or stolen money to the account holder, but you can only bear the loss yourself.

　　To ensure the security of our lottery and How to find it, the wallet is very important, as it is a tool for storing and using lottery and How to find it. Depending on the storage method, it can be divided into cold wallets and hot wallets. The way to distinguish between cold wallets and hot wallets is to see if they are connected to the internet. Both types of wallets have their own advantages and are very important. No matter which type of wallet, it needs to be carefully managed by us, the holders.

　　A cold wallet is an offline wallet used for storing cryptocurrency.

　　If you hold a large amount of cryptocurrency, storing idle funds in a cold wallet is a relatively safe choice, as an offline wallet, because it is not connected to the internet, and outsiders generally cannot access the location where the private key is stored through the network, thus avoiding hacker attacks or malware infections and other situations.

　　和冷钱包相反，热钱包是通过联网的存储的钱包。

　　热钱包是指互联网能够访问你私钥的钱包，热钱包往往是在线钱包的形式，使用热钱包时，最好在不同平台设置不同的密码。且开启二次认证以确保资产安全。一般而言，普通散户用得比较多的是热钱包，因为使用方便。而大户才会用冷钱包，因为资产庞大，预防黑客入侵的风险。

　　安全方面，热钱包不如冷钱包，联网功能使得热钱包在安全性方面稍显逊色。

　　2019年的5月，交易所币安就发生了被黑客攻击且从热钱包里面盗走7000个比特币的事情。但如果从便携方面考虑，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。

　　1）备份好私钥和助记词

　　对于数字钱包的安全管理，一定要做好私钥或助记词的备份及存储。切记助记词和私钥一定不要截图存在手机里或者在线保存在云盘中，不要复制粘贴收藏在社交平台上，也不要通过网络传输“私钥，助记词，密码，keystore。

　　2）不要下载来历不能的软件

　　不要随便下载来历不明的软件，特别是加密货币资产相关的，下载软件一定要通过官网跳转下载。假如你在这些途径输入了私钥，从技术上来说，很容易就能获取。

　　3）不要连接公共WiFi

　　以前听过用公共WiFi被人盗取了支付宝支付密码等，对lottery and How to find it 钱包来说也是同样道理，很容易在不经意间就被盗取了。

　　小编认为，应该根据各自的lottery and How to find it 资产情况来使用，少量的、经常用来交易的lottery and How to find it 可以放到热钱包中，就当平常的零钱用了；大量的价值高的lottery and How to find it 资产就放到冷钱包中，当作长期储存的资产。

　　对于资产较大的持有者而言，冷热钱包一起使用可以在满足便捷的同时，又隔离风险，更好地保障Online casino and How to find it 资产的安全。
