“9·11”恐怖袭击事件后，巴菲特制定了以下保险原则来预防黑天鹅事件：“第一，只接受能够正确评估衡量的风险（只待在自己的能力圈范围），再谨慎评估所有相关因素，包含发生概率很小的损失可能性在内，然后得出盈利的期望值。这些公司从来不以市场占有率为意，同时在看到同业为抢夺客户而杀价竞争或提供不合理的理赔条件时，也不会跃跃欲试。第二，要严格限制承接的业务规模，以确保公司由于单一意外事件及其相关联的事件而承担的累积理赔损失不会危及公司的清偿能力。要不遗余力地寻找任何看似毫不相关的风险之间可能存在的相关性。”

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
You can’t. What you can do, though, is use WhatsApp’s and Telegram’s web platforms to transfer stickers. It’s easy, but might take a while.Open WhatsApp in your browser, find a sticker you like in a chat, and right-click on it to save it as an image. The file won’t be a picture, though—it’s a webpage and will have a .webp extension. Don’t be scared, this is the way. Repeat this step to save as many stickers as you want.Then, open Telegram in your browser and go into your Saved messages chat. Just as you’d share a file with a friend, click the Share file button on the bottom left of the chat window (it looks like a dog-eared paper), and select the .webp files you downloaded. Click Open and you’ll see your stickers in your Saved messages chat. This is now your sticker depository. To use them, forward them as you would a message from one chat to the other: by clicking or long-pressing on the sticker, and then choosing Forward.
