That is what we will get if we are playing gambling. One person can win the game, while the other people are losing their money. It will happen like that without we can stop it.

Ikr. It seems all of those accounts are controlled by same person since i've seen he tipped from 1 account to other new account which just created. This guy do believe about superstition/myth if we can win a lot by create new account in gambling.
