Hands down: the wagering requirement! I won't name the site but I am truly irritated and won't be going there again.

I agree it may get tricky for house sometimes if user is solely using casino for routing funds so house has right to apply wagering requirement in such cases. But wagering requirement for every deposit, that's too much! I may have deposited 50 mBTC but after losing 8 mBTC in say, 4 straight bets, I may call it a day and decided to withdraw the remaining funds but boom, you are presented a requirement that you have to bet at least 50% of the deposit amount on single event! Man, I just lost 8 mBTC and you want me to bet another 25 on a single event before you give me rest of my money! I don't know what to say but that's clear-cut user manipulation even though you mentioned that in your 'terms & conditions' and I ticked that horrible checkbox!
