Yeah, but seriously - who is going to tell Elon Musk "Hey, would you please buy my cryoptocurrency??" Steem is still volatile, especially with all the conflict between Hive and Steem ecosystems. I am not on either side, my only priority is good content. But from what I understand about cryptocurrency - Steem is not what I would invest in. For me it would be Minero, Bitcoin or Ethereum. And since Elon Musk has more to gamble with - Bitcoin is the obvious choice.
