I guess mine options are not in the list.
I would buy
Electronics and
Travels!
For electronics I mean a new computer. A small one, to be able to take it anywhere and code wherever I want. Ah, and because mine my Macbook is getting older too.
For Travels, c'mon. Who doesn't like to travel?

I have started traveling so recently and I am kinda in love with it. Paying it with bitcoins would just be so... wow! I can't wait for the first travel I would do paying with money from it!
