This recent trend of top world billionaires and CEO's of top conglomerate including #bitcoin in their twitter bio will really do a lot of good and go a long way to promote acceptance and adoption first among their closest friends, family, those who see them as business and investment mentors and also those that see them as competition.
 This update further serves to say that these business giants and visionaries believe in the future of btc. It sends a strong statement to those still sitting on the fence and the critics  - "IF THESE BILLIONAIRES ARE BITCOIN BELIEVERS, WHO AM I NOT TO BELIEVE" .
