This was my first issue on FortuneJack when I won their slot multiplier contest here on BitcoinTalk. I'm about to withdraw $100 for profit, but the platform notes mention a minimum withdrawal of $150. Luckily, I managed to double the amount I want to withdraw. Why do some other casinos offer withdrawals without a minimum? What's the difference? $50 still quite big amount for min. withdrawal in my opinion. I know some casinos allow withdrawals as low as $20.
Every casino has their own policy, that's why we find the fact that there are differences for the minimum withdrawal amount. This
thread by Pmalek might be something useful for you as a reference about minimum withdrawal and withdrawal fee in many different casinos. You'll see there that there is even a site with 0.02btc minimum withdrawal. In this case FJ has just reduced their minimum withdrawal, so it is already better than before and maybe they may consider it to reduce it again in the future.
