it really depends on how they handle security in my view. if they do it very poor, and the user based is effected, then everyone will leave something similar like that one site called dicebitco.in that lost over night due to a supposedly a rogue employee.
it was a huge mess with people who invested on that site on the investor side. outside from the player side manipulation.
Dicebitco.in didn't have a security issue. Instead, they have been caught cheating, not just once but twice.
