Yea, we understand that it isn't a nice idea to play in a relatively new gambling sites. The longer and more reputable the better. If we all follow the rule of not investing till they last 2yrs. Who will be patronising them and how will they last upto 2yrs without patronage. It all boils down to being very careful.
I never prefer to use any new site either that is gambling site or that is currency exchange site. But Many people use new site too and that starts from nearest people of the site and also they become famous day by day as participant increase in the mean of time if there is a proper marketing and perfect support by the site.
Well, I am not against the use of the new site but again I will rather play on a reputable site than try to get a place on a brand new casino, quite a lot of new casinos face different challenges and some of them can not survive those challenge and it takes a long time before a new casino will get their fittings on the market. So one needs to do a review of a site before making any deposit.
