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.
You yourself mentioned the two most important reasons that influenced the development of online betting and basically the entire internet gambling. Consider the popularity of smartphones as well as the pandemic and lockdowns have made online gambling begin skyrocasting recently. There is no doubt that this is the future, but of course land-based casinos and bookmakers will continue to operate for a while, but I'm sure it will become less and less over time.
