It sure could be but I doubt any real rise will come of it. Maybe some people will use cryptos but I doubt it will cause a huge flair in crypto usage. I think the Olympics would be a better suited venue to increase awareness.
I also think that the impact might not be so pronounced except FIFA makes an official declaration for the adoption of Bitcoin or if the community was proactive in coming up with ways to incentivized the buying of tickets, food, accommodation, etc with Bitcoin.
