i've read about most of these tricks. however, i prefer online casinos mostly because of convenience
This year I think it would continue to be online itself, as the cases have not stopped and still continue to rise leading to fear among people to just go out and gamble in the casinos.
What more likely to happen is most physical casino will get web developers to design their own online casino, money would not be a problem for them as they don't pay electricity that much these past months. So I think there will be more of competition among these casino to attract players, more bonuses and more promotions to expect. Gambling won't stop.
Though you can wear mask, maintain physical distance but when it can be done online at your ease people may prefer that for the time being before everything gets normal and casinos would work the full fledge.
New normal may do but that does not avoid them from the virus, virus can easily attach to surfaces, they are playing cards or slots there are still a high chance of them getting the virus from any thing in physical casino.
That may actually be the next project of these physical casinos, create their own online sites and setting up/managing it would not be hard on their end. So yes, online gambling will boom in no time. They can get their players easily as they already have their own patrons so they will just send a message to these loyal patrons that they have online site and they are on the way.
