I think so. During the World Cup, some bookmakers made huge profits. Of course, they will make money seem legal by laundering money. Virtual currency is a good choice. Of course, this practice violates certain laws, but it will not stop their desire for benefits. A large number of BTC and ETH transactions will follow, and prices seem to rise accordingly.
This is my personal thought. This may be naive and perhaps sensitive. Welcome to discuss.
It can have effect. If you remember last time in the Winter Olympics, there are some countries that pay their athletes cryptocurrencies as part reward for their winning, if they win any medals in their respective events, therefore, it would not be a new idea if more countries would do the same after the World Cup, because surely, some footballers, considering how rich they are and having some money to burn, have already invested in cryptocurrency-related businesses.
