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 don't see how the world cup is correlated to the value of bitcoin and other cryptocurrencies. Sure, yes, a huge volume of fiat has been moving because of the world cup, but to whose hands? As far as i know this is between retailers, sports enthusiasts, or gambling loan sharks. Will are these people invested in crypto? I don't see any indication of why they would be.
I am however optimistic that we should see an uptrend really soon. The bears should be getting tired by now.
