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 good idea not to play in new gambling sites. Much better idea is that never play online gambling. There is no fun and entertainment in online gambling. Most of them are scams and you will always lose all your money there. If you are an addicted gambler you should visit regular casino for gambling. Atleast there are no scams and the games are not fixed.
If that's your impression of gambling sites, then you sure are gambling in the wrong websites. There's so much gambling sites that are provably fair and have been running for years already. Stop gambling in new gambling sites that promise you new things like free bets or money backs. Online gambling is safe and fair if you take the time to find the right gambling site for you.
Visiting an actual casino might not be a choice to some. Some likes gambling in background while they are working in their computer by running an autobetting script. Some are far from the city and casinos are pretty much inaccessible to them. Others simply have no casinos because it's illegal in their country. While most simply likes being in front of their computer gambling at the comfort of their homes while sipping some beer and munching some junk food. There are also the introverts who naturally don't like associating themselves with other people let alone people who are in casinos. The constant loud sound in casino, people cheering/yelling, and the sound betting machines make might overwhelm introverts.
At the end of the day, it still depends on the individual's preference.
