Will these steps promote mass adoption?
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" .
You are quite right, such a thing like - a famous person is rich and successful, he shares openly to the whole world that everything is ok and this coin is checked on his own experience, and how enticing it is you know. Psychologicaly people compare themselves with the successful ones and understand that this thing is trustworthy. Somehow directly or indirectly it makes a great impact on mass adoption and acceptance. And it is not only with Bitcoin, with brands of clothes or gadgets, or a lifestyle. It is a good trend for Bitcoin))
