It's no news that some football clubs might consider paying players in bitcoins sooner rather later with the continued surge of the currency football clubs like Southampton and Tottenham have partnerships with some Bitcoin firms and Southampton plays could be paid bonuses in bitcoins.
Could this be the way forward for football clubs in the future
I don't think it is the way forward. Rather, it is just an option for the players. Bitcoin has not yet reached to that level, where it can replace the value of money. Hence it is not yet a preferred choice for the players to get their salary. They probably wouldn't mind getting the bonuses in bitcoin, but it is still a distant future when the players will get the salary in bitcoins. So it's not a way forward as of now but may change in future if bitcoin really follows the stock-to-flow model and reach 1 million. Some players might want to have a little amount of bitcoin in their wallet looking at the future possibilities. But that's not going to become a trend anytime soon!
