My parents are simply not interested in knowing or using bitcoins as they are not internet savvy and prefer to stay away from it and they even don't prefer to use credit cards for online shopping as they have fear that it can hack their details so its very hard to convince them for bitcoins but its not too difficult to explain it to friends.
just like my parents. they are not so interested in internet, so is bitcoin, but my mother is just interested in calling me via social media. so I also find it difficult to explain it to them. probably if I told my mother that I got money from internet, she would ask me to stop from it.
however, I have ever explained general information about bitcoin to my friends, but it was confused for them. so I didn't keep explaining it.
