In where I am the offline gambling industry is doing better than the online,at least from what I see and because of people being about doubtful for the online gambling.To all my friends I have converted them to online players as I showed them with proof that the games that they were playing from providers like Admiral,Aristocrat and a couple of other providers are not worthy when I showed them the x10000 and up winnings from Pragmatic and others.
So yes the online gambling industry is probably everywhere except in Las Vegas and Maccau much bigger than that offline because of the ease of access to such platforms and somewhat of pseudo anonymity when you are playing online.
When you show a win of x10000 and above from Pragmatic, they will probably think how easy it is for someone to win big money from an online casino. They will start to learn how to play in online casinos and may come to you later to ask more questions.
Offline casinos are still running because they still have fans so the offline gambling business will not die. Apart from that, the number of offline gamblers will also increase because each person will choose where they will play gambling. And when they are shown that there is even an online casino, they will not immediately switch to playing gambling through online casinos but still use offline casinos.
This industry will keep on growing and there won't be an end to it. Lately after Apple's announcement of VR headset I feel a new wave of online VR casinos would be coming up. As we known gambling industry does have a reputation of quickly adopting new and emerging technologies. I am hoping they would quickly adapt to this emerging tech in order to enhance user experience. That being said we would see a decline in customer base of physical casino after the launch. It does make sense as to why would anyone visit a physical casino wherein you can experience it at your home. AI would play a crucial part in making VR more interactive and secure in the coming years. It is just the beginning of online gambling, it is going to grow by ten folds in the future.
Every new technological development will always be adjusted to each business industry and see which ones they can use to support their business work. If VR headsets have started to appear and are used, online VR casinos may appear but that will also depend on the headset's price because if the headset is still expensive, people may not want to buy it. People adopt new technologies according to the funds they have and if the price doesn't match the funds, they will wait for further developments. But even though online casinos may be able to grow tenfold, physical casinos will still be with us because people still love physical casinos.
