It will make them curious what you've given and just give an instruction on how to redeem it. Like if you're going to surprise her with a little amount of bitcoin with a seed.
Make sure that you'll add some instruction on how they can get your gift. I'm sure that they'll be happy to hold it as if it's going to make them cool that they hold btc.
Depending on our partner, if he is not very tech savvy, it seems that following the instructions to get Bitcoin will be complicated for him or her.
There are our partners become annoyed because of it, but if our partners really like technology and surprises, there's nothing wrong with giving
a surprise gift in the form of Bitcoin. But because I'm used to giving my partner on Valentine's Day it's something she likes, and of course
my partner doesn't understand Bitcoin and she seems less interested in technology too, so I will not give Bitcoin as a gift to her.
