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 a great idea. Using bitcoin as a wedding gift will create many surprises for the Bride and Groom. In addition, they can also reserve the bitcoin and wait for it to rise, until they need to sell it to use or they will join Bitcoin to get rich. And I will give them to my lover ^^
