Unfortunately, not every cryptocurrency casino provides customer support. In theory, you can contact them via some support channels such as email, phone, or live chat. But in practice, you can wait for the answer for hours. However, crypto casinos that care about their reputation have a customer support team that operates around the clock. They also provide multiple ways you can reach them out. If you deal with a trustworthy and reputable casino, you will probably be able to contact them even via social media. In this regard, it is recommended to avoid platforms that cannot provide high-quality customer service. And remember, live chat is a must for such websites.
