Actually Bitcoin doesn't need that kind of promotions which has to needed for new cryptocurrencies I mean new altcoin. But if say about the overall things then yes for increasing the demand of bitcoin it should be spread out all over the world all over the countries.
To see, various surveys have come out that still only two to three percent of the world's population knows about cryptocurrency. So in this case I think it is necessary to run awareness campaign in country to country to promote bitcoin or crypto currency.  Only then people will be aware of its positive and effective aspects. And this will attract people to invest here, the result of which will bring a positive spin on the market.
