Was there a reason to choose unknown bookmaker ?
New betting platform usually offer bonuses to attract new customers and this is the reason people like OP run after them. Maybe everyone is not clever like you and donot have sufficient knowledge about honest platforms. Suddenly they see lucrative promotions or get referral links from strangers and make their decision to register there.
Why some people goes to unknown sites after that they come here complaining?
In most cases victims come to share their story after getting scammed and they think that its the place where they will get their solution or someone will help him get his money back. Even few victims are already in Bitcointalk but take decision by their own without justifying properly. They just follow new platforms announcement and run after free bonus. There is no other reason IMO.
