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. Ultima Пассив от блокчейна 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 Ultima Пассив от блокчейна can see your username only if you post — your membership is not visible to anyone outside the group.

Ultima Пассив от блокчейна is a Telegram group for anyone interested in blockchain and income. Members can expect regular discussions on technology and investing, along with finance to research.
