With the way things are going and how these stable gambling sites are making huge profits, we will have hundreds of e-gambling sites in the next five years now that Cryptocurrency is on the adoption process, it's only a matter of time before the industry will shift to online gambling and the profit from the online gambling industry will be higher than gambling casinos.
That's only if the virus keeps spreading for months without any hope but in that case many economies will die and you'll have more things to worry about than looking for a new place to gamble.
I think that the virus will soon disappear just like sars did and the panic will disappear with it.
