I mean like on your local TV/radio stations, billboards,... Where the ad would 'simply' explain the concept and its advantages. Could this help to make bitcoin more popular?
EDIT: Or an even better question: should we try to make bitcoin more popular?
It is good idea, but what ever the idea we give the main point is , is it the bitcoin legit in your region, because most of the countrys are still taking bitcoin as illegal , so how can you advertise about bitcoin. Their are so many ways to promote Bitcoin but the main is that that country law should first accept the bitcoin , then automatically you can see how many users you will come asking about bitcoin.
One more think can be done is Online Shopping if they start to accept Bitcoin as their payment system then you can see the bticoin growing very soon year by year.
