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. Best Friends Ukraine&Köln 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 Best Friends Ukraine&Köln can see your username only if you post — your membership is not visible to anyone outside the group.

Best Friends Ukraine&Köln is a Telegram group for anyone interested in community and support. Members can expect regular discussions on ukraine and cologne, along with friendship to explore.

We verify every listing is publicly accessible, has a minimum member count, and exclude groups Telegram has marked as harmful. Best Friends Ukraine&Köln currently has 957 members and is marked as active, last verified 17 May 2026.
