Actually, I don't think that eSports gambling can become more popular than normal sports gambling.
We all know that, many games have been abandoned due to the coronavirus epidemic, many games have been postponed for several months, some games have started in a limited way.
so those who used to gamble in these games have nothing to do now. Again, many people have lost their jobs due to coronavirus, they are spending their leisure time now. so, they bet on eSports. after a few months, if all the sports are back to normal, the old sports gamblers will return to sports gambling again.
It's true that eSports gambling is become more famous than past, but it will never be more popular than sports gambling, at least I think so.
Well, this pandemic is just temporary once the vaccine is done and I know for sure that lots of gamblers will get back to their business once everything is fine and the lockdown is lift off. I still believe that normal sports betting is more popular than the eSport gambling but the possibility that eSport will become more popular is already there.
