I thought this casino was dead and no longer existing, wow, they automatically disappeared almost immediately after they ended their signature campaign on this forum, I am happy to see that they are still around, kicking and building..
Gamdom is one of big casinos, you can visit their twitter and you will see there are a lot users tweet, comment and share the Gamdom post [1]. Usain Bolt is the brand ambassador in this casino, they should be spent a huge amount money to him.
I think Gamdom become big wasn't from this forum, that's why their signature campaign doesn't really long since they didn't see a short term return.
