I believe that online casinos will gain ground over normal casinos due to the negative effect that covid19 is causing humanity. Countries are taking security measures so that people do not frequent places of crowds. If we realize these contingency measures are replaced by online activities such as work, studies, entertainment, etc.
The effect on the gambling world of this virus will be enormous, in my country casinos were already ordered to close their doors and I can see this happening all over the world, many people also like to bet on sports and for the most part that is not possible anymore, so the only alternative left for those that want to gamble is to do it online but I suppose there is even a decrease in the activity of online casinos as people prioritize other things like buying supplies in the case of an even greater emergency.
Corona has really shattered the gambling economy since people are unable to enjoy casinos and bet on sports because no sports are being held anywhere in the world. We common people are simply ordered to remain at homes and people have right now many other preferences than gambling.
