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. Тюмень | Бизнес | Крипта | Обмен 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 5,239 members, Тюмень | Бизнес | Крипта | Обмен is an established community — larger groups are generally less likely to be freshly created scam operations.
