关于TLS混淆，V2Ray用的是真TLS，即完全符合TLS协议；Shadowsocks的obfs和SSR的TLS混淆用的均为假TLS，即只模拟了部分TLS协议。真TLS的优势是服务器端防探测，第三方用任意的TLS数据包探测，V2Ray都能做出合理的响应，而假TLS则带有明显的特征。真TLS会有首次连接时进行一个两次通信(2-rtt)的握手，比起假TLS略慢，但之后的连接中，由于使用了缓存，握手不会有性能差异。

Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
The cloud-based messaging platform is also adding Anonymous Group Admins feature. As per Telegram, this feature is being introduced for safer protests. As per the Telegram blog post, users can “Toggle Remain Anonymous in Admin rights to enable Batman mode. The anonymized admin will be hidden in the list of group members, and their messages in the chat will be signed with the group name, similar to channel posts.”
