Bitcoin gambling is growing due to a few factors.
Transaction time is quite fast and users do not need to vertify themselves to gamble in bitcoin unlike in fiat.

I have played many online casinos, The fair casino is the casino give a transparent truth about their casino. I mean they can provide us their payout and bla bla bla.. 

I believe all casinos have their own adjustment and they could have some setting for their payout. There is no free lunch, The casinos provide entertainment for us and i do believe they need a return from the house edge or payout percentages on each various games we play, am i right? 

For me, before playing any casinos, i would love to know the true payout percentages. It's lovable if dreamlandcasino.com can give a clear statement for their payout percentage here. And it is better for some players there can give us reviews here.
