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. Берлін реклама 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.

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

Берлін реклама is a Telegram group for anyone interested in advertising and berlin. Members can expect regular discussions on events and services, along with promotions to learn more about.
