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.
I dont understand how World football cup championship in Russia is related to falling or rising of coins prices. But I dont think that the end of championship will help to recover the cryptocurrency market.
