When picking a site to bet on you should always see the site's reputation here on bitcointalk.
Picking gambling sites based on what reputation they have on this forum is welcome , but the ops list consists of sites that are fiat based and have no reputation thread there because they don't support crypto so how do we verify such a site .
It's important that you can withdraw your money just as easy as you can deposit, looking through the sites scam accusations will give some clues about the site but also see what users write about the site in the general chat.
I have seen many people having problems withdrawing their money from some of these sites, but what we forget is that it's our responsibility to read T&Cs before depositing or placing any bets to avoid such inconveniences which are preventable!
