Very many people have at one point in time or another heard about cryptocurrency but we still have so many yet to sign up for cryptocurrency. You can never know how great cryptocurrency is until you sign up for it and have the experience. More people are sure to sign up and have the experience as we move on.
Too many people know about cryptocurrency but still a large number do not know even the name of cryptocurrency. They need more time to understand and accept the importance of cryptocurrency. Now people use social media, print media and electronic media and these are all means to promote cryptocurrency all over the world easily an in less time.
In my community I think that only 2% people know about cryptocurrency because I am here for more than 1 year and I know how many people have invested in bitcoin and for how long they are in crypto world. Mote time needed for such people that do not aware of cryptocurrency and I am sure in the near future they will also put their money in crypto when they realize the importance and benefits of cryptocurrency.
