Some betting websites are shady.. I remember seeing a lot of scams related to dice, gambling, and even that I came to a conclusion.. Never trust a betting website because they are not operating to make us rich.. They work and keep alive by making you lose your funds.. I think that you should wait for more community engagement to know if the mentioned website is a scam platform.
Searching in this forum could solve your issue in ensuring that the site is shady or not. It's your choice if you want to trust a scam platform.
