I think this has something to do with the world cup because people are selling their assets for investment in world cup either gambling or so on.
therefore the demand for bitcoin and ethereum weakens.
Yes world cup may have some bad effect on bitcoin price, because people are still busy in football world cup, but i think that most of the people do not care for the world cup, they consider bitcoin as their business and therefore they continue trading bitcoin and other crypto currencies, i hope that after football world we will see a good increase in bitcoin price.
Is there any proof, how world cup is big impact in crypto fluctuation may be some gamblers are busy in this situation but most traders always monitoring our investment then only they will earn profit. Bitcoin price is currently green so all the peoples buy know if you think all are stay outside in this platform then how this will grow in the market.
