Particular, which CONCRETE advantages can the people get from BTC?
By people, I understand people of the world, not people of USA for whom the national currency is dollar. The people of the world have experienced devaluation of their national currency in numerous cases. For them bitcoin is the best option to stop the evaporation of their wealth.
We find Bitcoin to be the best option for people, but the sad thing is that they don't think like this. Some even see Bitcoin as the currency of criminals due to the negativity campaign from the media against Bitcoin. I just hope people will stop believing nonsense from the media, and start focusing on facts.
