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.
However, this is a rather laborious process. Just as when moving from one place to another, we risk losing some things, so when moving customers offline to online there is a risk that they will be lost. When a large casino announces the creation of an online cell, a lot of scam clones appear that will disorient and lure some customers to themselves. And given that the level of preparation for working with web applications is different for everyone, the percentage of trapped clients can be quite high.
I don't think most people will be trapped into clone sites if the casinos create their official online site and invite everyone from their physical casino itself but it is not going to happen in near future so there people might already moved to fiat or crypto online gambling sites to tackle lockdown boredom.
Not really because the clone site can look like the original site that can make them confusing to play gambling.
I think online gambling is already booming because I see in some advertisement which promoting the gambling website, but I think that the gambling website is accepting fiat.
But I think the crypto gambling website already appears in some advertisement, so that can make people curious, and they can join because crypto is a new thing for them.
When there is more advertisement about crypto gambling or fiat gambling, people will be excited to join because that will be entertainment for them in the lockdown or the new normal.
I don't really find any crypto gambling related ads on social media or Youtube like platforms from the official ads only I had seen poker sites and apps on various youtube ads that is why I said people already moved to online casinos with fiat so physical casnios will take time to establish their online community and get advertise them.
