in this case we will not know, if the football players are paid with bitcoin, and also we will not know, if the football players are paid using bitcoin, will they keep and hold it for a long time or will they be sold immediately as soon as the bitcoin has been received . so in this case I personally can not speculate on it all.
That means that you are not following updated news for a footballer that's why you need to be updated before saying a word on this topic
Sure they hold some coins for long times too like the JUV token CR7 hold it for about a year or more.
