Lots of gambling websites that provide news related to gambling or casino, just use the google search engine to search.
But most of the news and reviews about the casino I got from this bitcointalk forum. The reviews come from websites,
after all about casino reviews is mostly paid advertising, so don't be too 100% trusting the reviews on some gambling
websites.
If the reviews come from the website out there, we need to find out more about that gambling site because we don't know if they give an honest review. When we can see other reviews from the other website and don't give a good review, we can know the truth. If we can see the review from here, we can see that the review will come from the members who already tried the gambling site. Even if the site is legit, we need to limit our money to play on the gambling games.
