Why? Maybe because that bitcoin they dont hold it literaly.yes you can see it but you can not hold it.they dont know the big use of bitcoin nowadays. And maybe they just think of not secured while you have it in your wallet..they think they might be gone not knowing it. And they dont know yet how this was useful using easy transactions even far away..
The fact that bitcoin was more secure and safe in our wallet rather on our real fiat money..they dont know this is secure not to stole from some one..maybe they should know well first this bitcoin beforw they trust on it.well we also know that we can not please every one to love and trust bitcoin.but hopefully people know bitcpin and the big value of this to have it and keep it.in able for us to go on in progress...and in able for us to be in sucessful in the future.hopefully they will love it and known this well soon..
