Joining a public Telegram group carries no risk to your wallet or device by itself. The real risk in crypto groups is social engineering — unsolicited DMs from fake "admins" offering deals after you join. Casa dos Cursos is listed in our directory, but the rule applies everywhere: never respond to DMs from unknown accounts after joining any crypto group. Your phone number is never visible to other members unless you've made it public in your Telegram privacy settings. With 3,573 members, Casa dos Cursos is an established community — larger groups are generally less likely to be freshly created scam operations.

No. Telegram never notifies your contacts when you join or leave a group. Other members inside Casa dos Cursos can see your username only if you post — your membership is not visible to anyone outside the group.

Casa dos Cursos is a Telegram group for anyone interested in resources and tutorials. Members can expect regular discussions on learning and courses, along with education to discover.

We verify every listing is publicly accessible, has a minimum member count, and exclude groups Telegram has marked as harmful. Casa dos Cursos currently has 3,573 members and is marked as active.
