For me one thing is not clear, if tens of thousands of people play at 1xbit every day for huge amounts of money, so why would such a large casino as 1xBit cheat some small gambler?!
What proof do we have for this assertion? Where did you get the figures you quote? Do you have any examples of somebody who has an account at 1xBit playing with some real money and getting honest payouts if won? At least one such case would be very convincing, but there is none.
