官员称沃尔茨及其团队使用Gmail处理政府通讯
美国总统国家安全顾问迈克尔·沃尔茨及其团队被曝使用个人Gmail账户处理政府事务，涉及讨论敏感军事部署和武器系统细节，引发安全争议。《华盛顿邮报》获取的邮件显示，沃尔茨的助手通过Gmail与政府官员交换高度机密内容，包括现役武器系统技术性对话。
尽管国安会发言人称沃尔茨"从未通过开放账户发送机密信息"，但官员透露其曾通过Gmail发送非机密工作文件，如日程安排及文件。专家指出Gmail缺乏端到端加密，邮件可能在谷歌服务器等节点被截获，易遭黑客攻击或网络钓鱼威胁。

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
