You are free to believe which casino's review, he is simply suggesting you something good, you can do simple search with keyword "trustpilot" in this gambling board and you will see that most experienced gamblers will not use it as a reference because anyone can post a review there without providing any proof.
Especially after Trustpilot was acquired by Justin Sun, the man of drama and shady management on his business, it's harder to trust reviews on Trustpilot. You can still use it as reference but with more awareness about its bias and must check reviews from other sites then make comparison with Trustpilot's reviews. Don't automatically trust any review from any review website, not only Trustpilot, because they can be sponsored for doing this.
