Note: This guide intended only for the ones who’s more towards having privacy(Maybe AnoNyMity on telegram)

1) Don’t use your real number, use any burner numbers. Don’t use telegram based anonymous numbers[ Maybe good for you if you are interested in investment and get less limitations. This is 100 times better than using own number but burner number is best, cheap and also easy to rotate ].
2) Never use real IP.
3) Make sure you change these privacy settings:
- Disable peer to peer calling even for the ones in the contact list
- Hide your number from everyone
- Disable searching you through your number
- Disable generating link previews in secret chats
- Forwarded messages to nobody
4) If you intended to use a username, make sure it’s completely unique and never used. Avoid leaking your DoB year or mobile number ending digits in the username or using the same number sequence else where to your other social media account
5) Better to clear the chats in all the groups whenever you feel to.
6) Don’t use keyboard suggestions. Try to write the words from scratch.
7) Never talk about your alt ids anywhere.
8) Don’t join the same groups you join with your normal account
9) Never use bots like whisper for sensitive conversations . Use a custom one if possible or else stick to PM
10) Use limited words if you want to talk In a public group.
11) Using Once View or Secret Chats or Self Destruct doesn't mean others can't save those conversations.

Differentiation must be there between private and normal account

PS: If you are really a paranoid, don’t talk anything sensitive on telegram cloud chats except in the secret chats or else stick to Simplex[Duress Feature available which will let you put two passwords, one is for login and another one to self destruct chats😉]
