For now, BTC is such h huge digital currency, that it needs no sort of introduction because it is known to millions of people throughout the world and the centralization of bitcoin by the government could be the biggest awareness for the cryptocurrency. Other methods by which we can create awareness among people is by organising debates, campaign, printing pamphlets, hoardings and introduction of cryptocurrency to the youth could prove the great awareness for BTC because youth and cyrptos, both are asset for the planet.
I think I disagree with the words in bold. Bitcoin still needs a lot of introduction throughout the world. If you are from my part of the world, you will understand how difficult it is to introduce and explain Bitcoin to people. Sometimes I get snide remarks from people I try to introduce bitcoin. The government of my country makes it worse releasing negative statements once in a while about bitcoin and blockchain technology.
As it stands, the best way for me and the few others in my country to create awareness on bitcoin and blockchain technology is the proof of wealth that is made at each time bitcoin value increase.
