Is there anywhere i can check what the mining costs and how much dividens could make with 1000 bet for example? Apparently without an account or holding BET i can only see this.

And this doesn't really tell me if this is currently profitable to buy or not.

Hopefully, those images above would help you.
By the way, I have tried to visit the page (
https://earnbet.io/BET) without logging in first and I still can see all pieces of information on that page, you just need to scroll it down to see the info that you looking for.
