Every person has different point of view regarding the digital currencies. Many of my friends do not even know about bitcoins. Most of them says its just a fraud or a bubble. Even though i try to convince them by showing the proofs of how many people in the world are actually bitcoins and the possible future but still they do not trust it.
Yeah right, some of them are closed minded about cryptocurrencies and most of them dont really want to make investments, they just thought it will turn into scam soon.
Don't care of others if they do not know the worth of bitcoins. You and I know the worth and thats enough for us i guess. We cannot force anyone if anyone is not willing to accept.
