There are many people who are aware about it but don't want to invest their money into it as they have fear of loosing their money in something that they really don't know.
if a person is aware of bitcoin and know about bitocin. and still he is afraid to invest in bitocin. so its mean that he has no trust on bitcoin. and actually he do not know any thing about bitcoin.
come on dude,if that's the case,they just aware of their money,no one could predict the future,anything could be happening,seems they still in fear so not worthy to invest cause the fear could become a trouble in the future,and bitcoin is not just about investing
