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.
Yes it is not bad to try new gambling sites but simply people do not like to lose their money that's why they choose only old gambling sites. once the new gambling site started to receive good reviews then people show interest to play in new sites. But i don't think all gambling games are fixed, still sometimes when we lose money, in the long run, we feel like this.
I think for the new gambling site can give some free bonus for every people who visit their site so people can try to play the game and I see that there is gambling site which still using faucet for people to continue to get free coins. and if they can do this and many people play on their site, I think soon, they can get good reviews like you said and this will attract more people to come and play in their site. but I don't know if the gambling game is fixed because personally, I don't take attention to this and if I can play the game without any problem, I think it's enough for me.
