Hello,
This is not an official thread. We (gamba.com) have an official one prepared but have not posted it yet as we are still in beta. We want to ensure we are fully ready before posting our official thread and simultaneously starting our signature campaign with Little Mouse as our campaign manager.
If that's the case it then obvious that the op is no one but a referral bonus hunter who just created a telegram referral bot that new interested customers can through his create an account with your platform while he makes his bonuses for the referrals. Funny enough he made his post as though he was a direct official from gamb.com rather than stating the obvious.
With this information we anticipate to see your official thread any time soon, from what i saw in your site your casino seem offer a wide range of games so, it will be great to have you add to the number of gambling platforms already existing in the bitcointalk forum when your official ANN thread officially launch.
