I think there should also be a betting platform used to allow people to actually put down cryptos on the outcome of competitive video games. This can be done for games that allow observation as well as games without.
For instance, League of Legends would be similar to a horse race where bets can be made on multiple aspects and outcomes and be open to observers of the competition as well as players.
Games like Chess that are only viewable between the players competing could contribute to a winner-take-all pot. Though I love the concept of games, I feel Bingo is a little too old school to gain traction in the demographic with the largest crypto user-base--Males between the ages of 18-30.
