meh, like the another user said, this is nothing more than a way to gain free publicity, I mean, they could've easily paid the £384 in fiat, but I guess they wanted to bring attention to the club.
Iit is good that this news might help bring a positive light on bitcoin worldwide since this news has gained a lot of attention in the international media, but I don't see this becoming a new trend any time soon, at least not in professional football clubs.
But its still a good way to market their team and bitcoin. Maybe some of the players are really into crypto that's why they decided to accept it as way of investment as well. 50 cent did it in 2014, accepting bitcoin as payment for his album and made him richer in 2018.
As I have said, this is a win-win situation, bitcoin will be recognize, media have been portraying bitcoin in a negative way since the beginning, but kind of move will have fans notice that there are more positive side on bitcoin as well.
