Tbh, I still dont think it is a very good idea to give Bitcoin as a gift at wedding or other event that supposed to have romantic notes in it. The only acceptable scenario is when you both are deep into cryptocurrency. Otherwise it looks like a investment, than a present. Similar to case when on St. Valentines day you give her a ring, invite her to a restaurant with candles, and she gives you socks and shaving foam.
In our country, the type of gifts that can be received is something they will use to start their family, something they can use in the future, or if ever they necessarily need it. Normally, gifts such as money or life insurance were also being used as a gift. In my personal view, Bitcoin can be treated the same as I mentioned, providing an investment for your wife may not be romantic for you, but knowing that your partner has an investment plan for both of you, is also being romantic and being practical at the same time.
To be honest with you, i really wish i could see the romantic side of gifting a wife some bitcoin, even though this is one of the best gifts anybody can give to anyone, i still do not think this to be anywhere near romantic.
And talking of investment plan, investment plan is not a gift to your spouse, it's a responsibility, your responsibility as the man of the house, and also the woman's responsibility as the help meet to the man, having an investment plan is a basic family responsibility, that should not be seen as a gift given to another, as a man of the house, you can't be carrying out your responsibility to your family, and then see it as a gift you are giving to your family, makes no sense.
If ever i will be gifting my wife bitcoin, i would look for another physical gift she would very much appreciate, and gift it to her alongside the bitcoin, for bitcoin gifts alone is not romantic enough if at all.
