that's an interesting question!! I have ever thought about it before. But I'm thinking there are still many more meaningful gifts. 
And I will give them to my lover ^^
This is very interesting and I will try it later on our wedding anniversary. And I will give them to my lover ^^lol
I am sure that some people around here would have an upset girlfriend/fiance/wife if she was given Bitcoin as a gift...She would then see the price of it then get all happy..
