Do you know anything about them?
No not really
At first glance it looks like just any other (crypto) sportsbook and I guess they will have the same limit policy in the end. Winning bigger amounts is certainly possible and you won't get a limit right away, but after some withdrawals, your account will get checked and probably limited. Unless you are a longterm net loser on their site, then you are allowed to keep going even with big amounts, since you are a profitable customers, albeit some lucky hits here and there.
Problem with these crypto bookies is, that they have no expertise in sportsbetting and do nothing in-house. It's super easy to run a sportsbook nowadays, you just need some staff to monitor things, some IT guys, some support - the rest you can just buy, i.e. everything odds. It's just a money making machine, with the people in charge having no passion for sportsbetting I suppose. Thats why everyone who takes money out of the system is not welcome. Which is understandable to a certain extent, but annoying nonetheless.
Well in my time there I saw many whales and their awesome wins! If that means anything....
Tron is not so popular here on forum, not many people from here gamble using trons. At least it's my impression! I can say only good things about wink and betfury, two tron based casinos where I am active for longer!
If you try wink.org sports book I would definitely like to hear your opinion about them!
