I'm also new here, and would like to hear some proper answers as well.
I've been gambling for 10 years now and know that many online casinos offer huge welcome bonuses and other rewards to gain the attention of new users. Some welcome bonuses are equivalent to the initial deposit made. Although I'm aware of the fact that its just promotional stuff, I felt for this more than once, he-he:)
So I quess, you could check with any recently established casino as they offer alluring bonuses to get more players. But my expertise on this matter is limited:)
So I'd still want to hear some suggections from this community.
