Telegram is just a chatting applications like skype and i wonder how someone can bet using it.
Can you explain better on how this can be done because i am using telegram up to date and i belong to many groups on telegram.
He's not gambling on telegram, he received a message through telegram containing a link about a new gambling site that they advised OP to try out.
Seeing as OP hasn't replied with more info for clarification, I assume that he doesn't want any explanation anymore.
