https://t.me/Sellgameqt_bot?start=_tgr_Wxgacps3MDg...

That URL is a Telegram deep link that opens a bot named “Sell Game” with the username @Sellgameqt_bot. (Telegram)

What the ?start=... part means

The start=_tgr_Wxgacps3MDg0 portion is a start parameter (payload). When you press Start in Telegram, Telegram sends the bot a message like:

/start _tgr_Wxgacps3MDg0

Bots commonly use this payload for referrals, campaign tracking, or to jump you into a specific flow (the meaning is defined by the bot, not by Telegram). (GitHub Wiki Search)

Safety quick-check before you click “Start”

If you don’t fully trust whoever sent you the link:

• Don’t share SMS/2FA codes, seed phrases, wallet keys, or ID photos.
• Be wary if it asks you to deposit money/crypto or pay “fees” to withdraw.
• Check the bot profile for an official website/channel and see if independent sources mention it.

If you tell me what you’re trying to do with this link (verify if it’s legit, understand what it does, or troubleshoot something), I can give more targeted guidance.
