There is no generate address option available, and besides I can see my deposit address already. Clicking on withdraw gives me an error that I need to make a deposit first to generate the wallet. I am not going to include this site in my table due to the way it's set up and because they failed to show withdrawal information properly.
Make sure that if you are logged into your account or not. I haven't made any deposit yet but it shows me the withdrawal page while I'm logged into my account. And I'm getting an error message like you while I'm logged out of my account.
I just took a quick look at Futuur. I can't say I find the markets for the Olympic Games particularly appealing. They mostly have prediction markets on the overall tournament winners in particular sports, and that's it. Currently there are only 2 football markets on the whole site.
Any plan to add Futuur in the table? They are also crypto betting platform with some unique betting markets. Previously I have made
a reply about their withdrawal limits. Currently there are more than 50 football markets available (
