These events will likely only be canceled for around a month, so you can just look for alternatives.
I've heard that most boxing events will still be going on, as will MMA.
They both present some lucrative betting opportunities. Or you can take the time to learn statistical analysis or poker hands or something, move into a different game once you're up to speed.
I also heard that they might be extending the time of suspensions, but still no one knows, lets just hpe for the best. As for boxing, as long as we can, we should avoid too much people in contact, we might never know someone is a carrier, but doin online bet here wouldn't cause much hassle only for those who are present on the Live Community.
Even other sports or eSports tournament is being canceled due to COVID-19.
Try esports.
There are still some games that are on going although some events were cancelled. This is specific for Dota 2.
I find these a boring thing although I'm a fan of League of Legends. I might just play rather than watching.
