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. Avalon - Биржа Товаров / Услуг 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 Avalon - Биржа Товаров / Услуг can see your username only if you post — your membership is not visible to anyone outside the group.
We verify every listing is publicly accessible, has a minimum member count, and exclude groups Telegram has marked as harmful. Avalon - Биржа Товаров / Услуг currently has 88 members, last verified 13 Jul 2026. If you've joined Avalon - Биржа Товаров / Услуг and noticed something suspicious — a review on this page helps others stay safe.
