I think only a few people who know that cryptocurrency is very good and some others consider that cryptocurrency is very dangerous there may also be others who think that for now very few know the benefits of cryptocurrency.
A lot of people knows about cryptocurrency but most of them don't really understand this market. We cannot identify the exact number of true believers but we can notice that around us. Example here in my place, 4 out of 10 knows about this market and half of it are still not investing. This market is great, and this should be understand by everyone so they can enjoy the benefits of having this technology.
