Some of the most prominent registry websites in this space, like Zola and Honeyfund, say that they've started to see couples register for gifts in the way of cryptocurrency.
And the average cash gift is said to be around $160 for weddings in the US.
Some suggest that you shouldn't give cryptocurrency to another person unless you are sure that they already use it or are aware of what to do with it.
However, if they don't know what cryptocurrency is yet and they haven't used it before, giving it to them might provide incentive for them to want to get to know what it is.
If they want to access their funds then they would need to try and learn how to use it. After they learn how to access their gift funds, they might continue to use it; seeing as how easy it was for them to begin using it in the first place.
