You can add it the same way you would as a member in your Telegram group by searching for "MorphChat" and can start using it:
Add member, search for "MorphChat"
the member bot will popup, select it and add to your group.
MorphChat is a highly engaging bot that allows your members to tip, pay for products or services using different tokens.
Once the bot is added you can start interacting with the bot by replying to members with /tip 10 METM or /buy 10 BEEF or /send 10 HOT for example which will help build a lot of excitement and create a nice warm sharing environment within a TG group.
