We have some hot data for you, which you only can get here, in Botan channel.
Have you thought about whether your bot’s retention is high or low, compared to other bots?
Here is the answer: the average D7 retention for bots is 9%, which means that 9% of users send a message to the bot seven days after the first message.
You can measure retention of your bot with Botan http://botan.io/?c=cr using Cohort report tab in full web interface.
Here is a bonus track, retention comparison between bots and apps.

✳️ TIPS | LINK PREVIEW ✳️
🌐 TELEGRAM LINK PREVIEW SYSTEM 🌐
‼️ The parsing/preview system is server-based, so it cannot work in Secret Chats. The parsing system is managed locally in secret chats. ‼️
➡️ All links to Twitter tweets, Instagram photos and YouTube videos are beautifully rendered so that you’ll see what the link is all about before opening it.Once you paste a URL to the message input field, Telegram will start analyzing the link and getting a preview for it. If you prefer to send a particular message without the preview, just tap the x to remove it.
___________________________
❓How does Link Preview technically work?
➡️Link Preview is generated server-side. Means, that users send the link to the server, server is fetching infos via API, creates a rich text preview and sends it back to the user. IP of server is shown to the API, not the IP address of the user.
___________________________
❓ Optimizing web pages to work with Link Preview
➡️ Telegram is using the Open Graph protocol (http://ogp.me/), so it's very easy to update existing web pages to support rich link summaries. Make sure that you can edit the source code of your website and add some <meta> tags in the <head>.
___________________________
‼️ Make sure you do not block access to your website. The robots noindex meta tag forbids the Telegram server to fetch information from your website. If you did it once, the Telegram server will remember that it's forbidden to fetch it. This may change in the future. But for now, you would need to change your URL.

✳️ TELEGRAM | TIPS ✳️
☎️ When is my phone number visible ☎️
1⃣ If you add someone (adding the person as a phone contact) and write them a message, the recipient will be able to see your number.
2⃣ If you contact another user via a username, forwarded message or group, your numbers remain 'unknown', until shared.
3⃣ Once the number is shared, you will always see it — even if you delete it from your contacts list. No reason to hide it again.

✳️ SECURITY | CRYPTOGRAPHY ✳️
‼️ CONCLUSIONS ‼️
▶️ In this work we have shown that Telegram, with its use of aging primitives, does not manage to provide data integrity of ciphertexts nor authenticated encryption, and is vulnerable to chosen-ciphertext attacks.
▶️ The attempt to mitigate known attacks has introduced new vulnerabilities, and we suggest that the Telegram team updates its protocol to use strong, modern primitives.
▶️ For message authentication codes it should use a good HMAC, use a proper key derivation function, and up date the key exchange to use elliptic curve Diffie-Hellman based on Curve25519. Telegram has a great emphasis on computational performance of its protocol, which is why CTR with its parallelization seems to be the logical choice of encryption mode. We suggest using CTR instead of IGE mode, as IGE offers no benefits over CTR.
▶️Overall, we can conclude yet again that homegrown cryptography is a bad approach.
