Merry Christmas mate. Most of my friends and family know not to ask, or don't even know Bitcoin exists so don't know to ask.

Good luck with handling your festive season enquiries.

My family is pretty nosy too, but all you have to do is start talking about the technical aspects of blockchain decentralisation and how it will disrupt the entire financial/political systems.....and their eyes will glaze over right in front of you. They won't ask you any more questions about Bitcoin after that :)
