Unfortunately, I don't have a wife yet.
If I ever get a wife, I would like to give her Bitcoin as a gift like you did.
I also don't have a wife like you, and hope that one day when we get a partner, we can both do the same things OP did.
The value of Bitcoin will be better than that of gold jewelry.
Of course this will be something romantic in a wedding because it will be different from other weddings. Indeed, in many countries the culture will definitely be different, we also need to pay attention, if in a country that prohibits bitcoin this will certainly be a problem. Thankfully in my country it is not prohibited, this is a good opportunity to plan because bitcoin is also like gold even though bitcoin is not physically real, but if your future wife already understands about bitcoin, she will definitely be happy to accept a bitcoin dowry rather than gold or diamonds.
