Joining a public Telegram group carries no risk to your wallet or device by itself.

Your phone number is never visible to other members unless you've made it public in your Telegram privacy settings. With 1,165 members, Барахолка Кёльн 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 Барахолка Кёльн can see your username only if you post — your membership is not visible to anyone outside the group.
