I wouldn't place my bets on those new gambling sites. I am not into trying out new sites and give feedback if they are good or not. Let the others spot which gambling sites are fixed or gives a sh*tty service, but for nowlook at those that are online for more than a year and received positive feedback.
It is not bad to try new sites but I guess you really need to study them first. This is the reason why new gambling sites is so hard to be popular.
They have a lot of other gambling sites competencies and that competencies are the used gambling sites by the users. They trust these sites and it is hard for thrm to try new gambling sites.
