Well this site looks different than others, betting platforms are unique. I have just placed a bet with the free coins that I have in my account. I don't believe that Elon Musk's SpaceX will be able to take human to Mars by the end of 2024. Recently their rocket failed to land successfully after launching and crashed.
BTW, I'm also unable to find out the withdrawal option as 'Lordhermes' said above. Maybe without having balance in account we can't see the withdrawal option, right? I was searching for the withdrawal fee at your site. In terms and conditions page I can see that
4.1 In order to bet real money using the App, you need to deposit funds into your account (Account Balance); deposits can be made into the Account Balance by means of the following Payment Methods: Skrill and Neteller.
There is no information about bitcoin deposit and withdrawal in T&C page. Even I can't see FAQ page at your website. It's inside the community page and there you have provided information about bitcoin deposit and withdrawal. At the website only bitcoin is available as real money for depositing, play with it and withdrawal. But in the terms page it saying Skrill and Neteller is the payment method. Which is a bit confusional. OP, can you clarify these things?
