Reputation is built over time, so online casinos that are known reputable here in the forum, I would say, is indeed reputable and trustworthy. But yes, there are so many scam casinos just like the known one in this forum. So before you signed up and tempted with the clickbaits or promos, try to search the feedback or players' reviews and you will have insights on how they are treating their players. In this gambling board alone, you can check the trust summary of the casino's rep and you will get the idea if they are indeed worthy or not.
I actually meant the same thing, currently new crypto online casinos are being created all the time but most of them are scammers. In many cases, it has been seen that they promote themselves by hiring big influencers, and if we talk about social media, it has become like a cancer nowadays, in almost every advertisement, we see promotions of new gambling sites.
And for this reason, I think that for fair play in gambling, one should follow community-based reviews and then choose the right and reportable casino.
