promoting bitcoin is easy, but some people do not believe that bitcoin does promise real income and there are some people who do not understand how bitcoin works.
i think that they need some good tutorial and then they will surely know about the importance of bitcoin, bitcoin is the only currency from which one can get a very good profit, but in fact most of the people still do not have any idea about it, they need to introduce bitcoin to them so that they can understand the importance of bitcoin and start using it.
