To be honest, it's hard to determine casino's trustworthiness by only looking at reviews. Many people post a negative review if they lose and don't profit from casino and that's wrong, that doesn't make casino a scam company. If casino pays on time and has no technical problems with good customer support and response time, then they deserve positive reviews but people rarely consider these criterias.
Critic reviews and user reviews do help to a certain extent(References), but your own review is what should matter the most. You should invest small amounts initially and check if you are satisfied with all aspects of the crypto gambling site that you are interested in.
If you are satisfied, you should proceed to invest bigger amounts. If not, you should avoid the site. Simple!
Any reviews given is really helpful since it can determine how trusted they are or not. Even if we can read some fake reviews still we can determine if they are using bots or paid review since we can read out of this world statement came from those bots. Our review is really the most important thing there since we could personally know if the casino is legitimate or not since we could provably see a legit review especially if they have a thread posted since there's a lot of legitimate people well tell their experience about the casino we are trying to know their reputation.
Also its automatic and we can't think any further especially if they can't provide a quality service since we can quit immediately. Unlike those trusted platform where we can enjoy and also use the amount we can afford to lose but if they can afford those big amount then its up for them to decide.
