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.
Do anyone catch up any changes that related to the end of world football cup in Russia. I didn't see any connections. And really I don't know why so many guys are talking about it. On my mind there is no any significant connection.
