I have told them a lot about Duelbits and some are already beginning to try it, but since it is with cryptocurrency, they sometimes mistrust it because they do not know it very well.
True, there are countries that are restriction by this gambling platform including the place that I live in. But I don't bother to use VPN just to circumvent it because sooner or later it might give me a big problem in the future. So the case with casino, they know which countries ban online platform so they won't take that big risk specially if they have the reputation already. I guess @danadc you should at least open their eyes first regarding crypto before you open their eyes about gambling, just saying.
