This kind of promotion or maybe just a post from a famous star is a good and bad news. Good in which bitcoin will be promoted and more and more people will using it especially the followers of the said celebrity. On the other hand, those people would love to do bitcoin just for them to follow the trend, and it is not good especially of they only do it for nothing. Bitcoin needs people who are interested and willing to learn with this. Bit to sum up, soon bitcoin will be popular and people will understand it, we only need to have patience.
