The essence of the bot:
A user has read your list of advantages.
They click "Buy subscription," after which they are given a button with a link to payment. They pay and return back, and the bot provides a link in the channel. For one entry for that user, for one entry so that no one else enters!
Payment is checked automatically via API from the payment system.
Also, the bot has an admin menu that shows how many users have purchased (in short, statistics), and the ability to send broadcasts to all users in the bot, which adds a good plus to the functionality.
