Family members can go fuck themselves to be honest. When I was younger a member of my own close family stole £25000 off me.
I told my Dad (it wasnt him) I was going to report said guilty family member to the Police so he gave it to me from his own savings in the end to stop me.
Moral of the story - Be VERY careful giving any cunt your private key(s) as you never know what kind of financial trouble they may get into in the future & steal your coins.
My girlfriend (of 10 years) knows how to sell my bitcoins & the password to my wallets, I trust her & her alone really.
