People nowadays bet more online than in physical objects - casinos, they are given the opportunity to bet in the comfort of their homes, without having to leave their homes and without the cost of transportation and accommodation.
or because it started with the increasingly difficult global COVID-19 situation, and more and more countries are advising or even banning their citizens from leaving their homes, and people are spending more and more time at home with their phones and internet now. And this is also the reason why the online gaming business is booming, because people have nowhere to go.
and whether the success of online gambling may affect casino or physical gambling.
It may affect but not to the point that physical casinos will cease their operation, there are always loyal followers of physical casinos majority of these are tourists who want or get used to the ambiance of physical casinos they are not here to play games they are here to meet new friends
listen to the music and see people talk to them these are extrovert people who want to mingle with people and physical casinos are one of the places.
Physical casino will surely remain since for sure many rich person prefer the atmosphere of physical casino than online, but maybe this online things take a big hit for now because many people don't have a choice because the pandemic hit and the only one available is online gambling. I don't think gamblers are there to make new friends on online gambling casino but for sure they are their to satisfy theirself by playing as well some people are there for competition or just want to have a thrill.
