I don't think there are any valid reason to continue gambling as it will not make people rich but it will just make people lose their hard earned money. For me only people that still thinks they can win good amount are still playing
For security purposes i wouldn't like to show you my latest win from Windice.io, there are thousands of gamblers who have dedicated some time for gambling and yet still cashing out on regular basis, you could be like them if you will embrace it. Although not all time you win but when you are good, your winnings swallow up your looses. With this, you still pretty have more reasons to continue gambling.
