The decision isn't coming out of the blue. While Cuban warned that bitcoin was in a bubble back in June, he also invested in it (not to mention a blockchain fund and Unikrn's digital tokens) before 2017 was over. He sees enough of a future in cryptocurrency that it only makes sense for his team to support it. You might not see other teams or leagues rushing to follow suit, but it does represent a vote of confidence for the emerging technology.

Next season. — Mark Cuban (@mcuban) January 16, 2018
