So let me hear what you are looking for in online Bitcoin casino's...
If we neglect the design ,layout and performance then reputation would be my first priority to gamble at any casino.
I should have the satisfaction that i will be paid if i win some amount of coins,
after all what is the point of best chat and stuff if it is not going to pay you that you deserve by saying some bullshit story and claim that you knew the server seed.
That is for sure. You will get paid when you win, is there any problem with that thing? I guess all gambling are sure paying you when you win but sometimes there is only a little bit of delay because of the new site so they need to arrange many things. And active chat is some online betting is needed. Why? Because sometimes there are some people that really kind enough to share their things like strategy or may be some coins because of their big winning. And one more thing you will not be boring to play at there. These things looks simple but that is a must
