Most of us who gamble for crypto will continue with that, we will not return to fiat gambling, and for sure we are not coming back to physical casinos. Corona can't touch us!
Some would still gamble in physical casinos as online gambling gives different than gambling in a physical casinos, especially if a gambler is really investing his time more in physical casinos, even if the virus is still here but the casinos will open, I'm sure a lot of people will do the usual things they do.
However, for fiat online gambling, I think crypto gambling is better, I was once a fiat online gambler but when I tried crypto gambling, I never come back in fiat since I find crypto gambling easy and it's competitive to fiat gambling sites as well.
That's the bottom line, we discovered crypto gambling and there's no returning to fiat. Once we all were fiat gamblers (at least we as older generation +35), on and offline fiat gamblers! Now even if I would have fiat for gambling I would buy some crypto and I would gamble with crypto!
Experience is different, but as I get older I enjoy comfort of my home more than I enjoy dressing and going out. Physical casinos will always be there, for people who like that, for new generations to get a taste of it, but for many of us that is a thing of the past!
