How can you say it is wrong?
It is legal in most western countries, and casinos pay taxes to government, so money can be reused to the society, it is a good way to get money from the rich people and spend money on the poor, it is a good circulation and social action.
And there are less than or more than 10% people get rich from casinos, less than 1% people get ridiculous amount of money from casinos, and of course more than half of gamblers lost money there. We should know how to control ourselves.
I have earned over 15btc from gambling, that's good and IMO I will earn profit in long term.
