Why not you can give bitcoin as a wedding gift , in the future bitcoin will be a kind of very valuable item.
I would not give bitcoin as a wedding gift. Because I'm not so rich and a little greedy. But in general it is a wonderful gift and no one would have refused it. This gift will cost more and more day by day.
to me i am already married otherwise nothing was wrong there. in fact i have already given go may gifts to my wife that i already bought from the profit of bitcoin. in fact my wife know about bitcoin very much and even she is also involve in trading altcoin and getting good profit from there, we some time discuss different issues related to bitcoin.
