Do you think celebrities in the mainstream world are still using Bitcoin for their own benefit? If so, which famous people are deeply into Bitcoin right now? I'd love to see someone like Keanu Reeves, Microsoft's Satya Nadella, or even Apple's Tim Cook using (and patronizing) Bitcoin someday. At such degree, I think Bitcoin would've reached massive adoption within the mainstream world. Thoughts? 
What any reason would a celebrity have in participating in cryptocurrency. Like many of us I think they are in for profit. Company hires advertisers and known individual to promote their services, so probably that is one reason why known personalities are surfacing now telling their audience that they are using Bitcoin or support cryptocurrency. Though they have their profit in it, it is very good for crypto community because it will help in accelerating adoption. Imagine if their fan follow them in using and participating in crypto market activities, that will be a good boost to the industry.
