I really don't know if hearing bitcoin shills from a person like Kanye is a good thing; knowing that Kanye recently made some 'interesting' and definitely questionable statements saying that "slavery is a choice". Any publicity is good publicity, I guess?
Mentions from popular people can in a way help the spread the popularity of Bitcoin which can lead soon for it becoming a household name just like having a dollar or a euro. This is a good thing so that people will not anymore be looking at Bitcoin as sort of a mysterious object that has to be avoided all because some people are talking about it as a tool by the scammers or even as a way to finance terrorism.
