I'd advise strongly against using Fortunejack. This malicious website has refused to let me withdraw my winnings. I will do everything I can to steer others away from this scam casino.
I started with a deposit of a few btc and eventually turned it into 19 btc but they will not let me have access to my winnings!!!
Support has been zero help, STAY AWAY FROM THIS SCAM CASINO
You're not the only one :
https://bitcointalk.org/index.php?topic=4482056.0 Apparently, the support is going to sort everything out by Monday. And FortuneJack being an 'unreliable' place to play is an old-news. You might as well need to post your conversations you had with their support here for you to be taken seriously.Not that I care but from their campaign manager,
Post some proof if you want anyone to take this seriously.
