Brief overview
Telegram has a lot of video content (interviews, science or training videos), but you don't always have time to watch them. One button that gives a brief overview of a 30 minute video is very handy. The text can be copied if necessary.

Channel subnoscriptions
Creators of helpful content spend time to make their work useful. In Telegram, the user can decide to gift such creators a monthly subnoscription, which will be a motivation to create even better content. Or it is possible to buy the required content by one-time purchase.
No credit card, just TON and USDT

Donations
Content creators in Telegram channels can post truly great information. Administrators, in turn, can help in chat or answer users' questions. Why not give the user the opportunity to thank them? Anonymously or publicly. And yes, as always, only TON or USDT
