Because no one guides and teaches people what bitcoins are. Many people just discovered bitcoin because of the search. I wonder if it will be revealed on tv and internet so many people will know it
I agree, just a little help from the media and bitcoin's popularity will skyrocket. Although it makes me wonder since them advertising bitcoin could be achieved way sooner how come the media didn't make it mainstream, it seems to me they're threatened by bitcoin or else somethings stopping it from gaining further popularity.
