Some tech-savvy wedding-goers are gifting the digital currency to new couples. Honeyfund, a honeymoon registry that allows guests to give cash rather than gifts, has seen more than a dozen customers donate in bitcoin, said chief executive officer and co-founder Sara Margulis. In recent years, more than a dozen customers have chosen to route donations to the site from bitcoin wallets. Zola, a wedding registry website, has had just two cash funds created for bitcoins since 2013, a spokeswoman said. "I would expect it to pop more as millennials come into the wedding age,” Honeyfund’s Margulis said. “It’s something you will do if your friends and family are already into bitcoin.
Bitcoin as an retirement plan, bitcoin to secure the future of your kids, and now bitcoin as a wedding gift. Whether or not bitcoin replaces cash in future, it looks like the trend of gifting bitcoin instead of cash at weddings is definitely going to catch up and more wedding registeries would be adding bitcoin as a gifting option.
Avoid using a wedding gift "as an opportunity to proselytize a technology you personally believe in, but the recipient could not care less about."
People who are not into bitcoin might not appreciate getting a volatile currency as a gift, and might never use it, thus adding it to the list of lost coins, but I think people who are already using bitcoin or would most probably use it in future then bitcoin instead of cash is the apt wedding gift for them.
http://www.marketwatch.com/story/would-you-give-bitcoin-as-a-wedding-gift-2017-06-27Have to disagree with the statement that if you give bitcoin as a gift to people who don't know about bitcoin, it's not appropriate. And you should only give bitcoin to those who actually use it.
Of course, if you just leave them a private key and that's it, then the newlyweds aren't going to know anything about how to access the funds that are secured inside. What I would do is to include a wallet recovery seed hidden inside a card(perhaps bolding the words that make up the recovery phrase) and give clear instructions of how to use it.
Not only will it be interesting and adventurous for them to open and access the bitcoins, you are also introducing someone new to bitcoin, which is always a good thing.
