There is nothing wrong with gambling gamblers trying online casino games. They may also like it and this is their first time entertaining before the situation subsides.
You are right, during this difficulty most of the people will attract to online casino games, they can spend their free time on gambling. Instead of going outside. I don't find anything negative in sports betting because now due to the situation of the Corno Virus many people are staying away from it, so people who gambled on sports betting will return once they start again.
If someone is into sports gambling then for him/her it is very hard to adjust to online gambling games. I am sure many of you here will agree. Sports gambling is a completely different niche as the outcome here is not decided by the house but the actual game.
No one knows when live sports will resume for now it has to wait as lives of people matter more than entertainment.
