The URL provided isn't secure and it looks like self made platform. There were more trusted gambling platforms providing the best crash game. Good is to stay away from such attempts of new platforms that are not secure and doesn't have a perfect process of development and promotion.
The site started with https, the s means it has SSL or TLS certificate, and it means it is secure. But it could likely be a self-made one and able to to scam people just like fake gambling site. All of the fake sites that belongs to scammers these days have SSL or TLS certificate and are secure, but they can be used to scam and this likely might be another one of them.
As for me, the site do not have any qualification that I can use to recommend it than being a scam site that people should avoid.
If it were a site that had just launched, I would be impressed by how I could see the number of bitcoins already won by some people at the bottom of the site. Few people would spend so much on a new casino site on bitcoin gambling.
And seeing your site's registration time, 2022-06-29, makes me suspicious of the number of bitcoins already on your site. But I don't know.
You are funny, it is their site, all the money won could be fake. Most likely fake.
