I want to answer one question about this OP. What are people doing now? Perhaps, they are concerned not in sports gambling, they might be playing card games, slots, dices, and other fun alternative gambling games aside from betting in sports, or the worst part is not gambling at all.
People are not affected without gambling, its the gambling sites because they are losing money while people were able to save money at this time.
So somehow, this helps people to save financially while the site owner will have to accept that their income will reduce.
With the lack of income these days, there is a tendency that people might stop gambling for a while, and to focus their concern about their necessities, their needs to survive.
But for people who are earning online like us, mostly we still bet especially in crypto gambling sites. Such as what I usually play, Hi-Lo, Dice games, black jack and poker.
True, earning money now is difficult as most of us are ordered to stay at home, this is a big hindrance and actually those who earn are those people who work online, however, it's still not good to be aggressive in gambling as working online is not stable.
