Bitcoin needs more quality publicity. Very many people, especially in developing countries, have never heard of Bitcoin at all. And if they did, they do not understand what kind of phenomenon it is. Therefore Bitcoin also needs a correct interpretation. Information about crypto currency must be presented clearly and as simply as possible. And it is also necessary to emphasize the positive consequences of using cryptos both for each individual and for society as a whole. When people see exactly what they can benefit from this or that project, they begin to be interested in it.
