For regular gamblers though the online casino is always the feasible option.
I agree with this, those who still visit offline casinos are doing it for just some mood change or as a status symbol.
For people who see it as an opportunity to make money, they will compare both options. With more and more online websites entering this field, the competition among online casino is also increasing. Thus, they give these tempting offers from time to time to attract more players.
Those who are busy in life but still love to gamble, online gambling is much possible for them and yeah more online casinos are now working and they continues to attract more players which I think more risky compare to the physical casinos. Traditional gambling may not be good enough for some gamblers and this is why they are trying to play online which has more option to play.
