I think because Bitcoin really is something too vague , unrealistic . Even people who have knowledge of information technology are hard to understand let alone those who do not know anything about computers
not only vague, bitcoin is complex too.
but it certainly is not unrealistic.. of course people might think it is unrealistic the first time they hear about it, but it will change after they do a little reading about bitcoin
and one does not have to learn how crypto technology works to use bitcoin.
Yes, I absolutely agree with you . Even my family , no one believe me though I tried to explain to them whenever possible. Sometime, I also don't understand what i said . LOL
