I don't think bitcoin has anything to do with the World Cup.
Because there are many specialized gambling altcoin, there is no need for bitcoin.
I asked this question: When setting up a betting trading platform, is it easier for BTC to win the trust with participants or the tokens of the platform? I think it is BTC because more players will first choose to hold it, and secondly whether it will consider whether Buying its tokens, I think this is a regular judgment, of course, this is just my opinion.Because there are many specialized gambling altcoin, there is no need for bitcoin.
