Don't sell your Bitcoin to buy stuffs that will perish few days or weeks after Christmas.
The worst advice I've read from high rank accounts in this forum, you're don't know how important Christmas day for the one you love. Let's say you want to give a something to the one who you're rarely met, but you didn't want to sold your Bitcoin to buy the lovely stuff for her. You didn't give anything to her and just giving a useless text, but after then she will block you since she already with the other guy.
After you know it, you become depressed and don't have any reason to life just because you're don't want to sold your coin to buy a little thing.
