Where can I get a list of all-all open groups in Telegram?

Question

Parsing

Tell me, is it possible to implement this, get all the created open telegram chats, groups (not channels).

Answer 1

1. Buy Telegram with giblets and immediately get full access. If you have enough money, you can negotiate.
   
2. Parse all open sources for references to groups. But there is a high probability that in this way you can miss a lot.
