What makes a new crypto casino trustworthy in your eyes?
Having no KYC is definitely one of the many reasons that can attract gamblers to new online casinos. Being able to deposit and withdraw anytime they want without undergoing a verification process can help them feel convenient and keep their privacy as much as they want. There are also other things, of course, looking for the gambling license that they will check. Most of the time, they want to verify this to have an idea of regulatory framework behind the casino.
Another thing is the promotions and bonuses, this can help to encourage new possible users to spend more time exploring the online casino and possibly find a suitable game for them to enjoy. Sometimes, the terms for those bonuses is also important for them to consider whether the wagering requirements, max withdrawals, types of games, and other possible restrictions is worth their time.
To have an active live chat support can also help to build trust for an online casino. Issues concerning deposits, withdrawals, or other types of unnexpected issues csn happen, having a support to be able to respond and solved the issues quickly is important. Or even if the issue can't be solved instantly, having to receive a clear explanation from a support and to continue to receive updates regarding the concern is highly appreciated by all players.
And most especially is to build a positive reputation here in Bitcointalk. We all know that trust and reputation has to be earned over time. It's not something you can earn by simply creating an announcement thread and offer bonus for newly registered users. You can earn it depending on your actions and how you accomodate users. For example is how you respond to users if ever they have complaints, or if a user has a reasonable request, if they have a suggestion for the better of the casino, and how the team communicates openly to issues that can possibly happen. Because I think that even if there's a negative feedback, it can be used as an opportunity to build trust if you happen to handle it properly. There's no perfect casino, anyone knows that. What differentiate each of them is how the team would react and take action when something unexpected or something that doesn't go according to their plan.
