Can I gift Bitcoin to young family? Many years ago I looked into gifting 1BTC to each of my God sons, who had just been born. That gift would be worth a fair bit today, but I didn't do it because I couldn't figure it out.
How could I do this today? Remember, the recipient is 0 years old and can't upload their passport :)
Gifting Bitcoin to novice users is difficult. First, your gift is tied to an obligation. In order to make use of it, they need to invest time to understand it and how to access it. This causes such gifts often to not properly connect. Secondly, the Bitcoin gift is often forgotten about because the recipient doesn't have an immediate use for it. Often Bitcoin gifts are somewhat impersonal (e.g. a paperwallet similar to a gift voucher), so they tend to get displaced. Optimally, the gift is personal and unique enough to be kept track of as well as hardy enough to survive until the recipients interest is piqued.
This brings us to another issue. The instructions how to use the Bitcoin gift must be sufficiently accessible and longlasting that a novice users can follow them now or in two decades. And they must be stored with the gift! On the other hand, it should be safe against being stolen through casual observation, like e.g. cleaning helpers. Even using some service is hit-and-miss: the space is only 11 years old, nobody knows which services will still be around in 12–16 years when your god sons get interested?
I surmise that you might have the best chances of success by investing significant effort to make your gift very personal (ensuring that it is treasured) and find a way to integrate instructions with the gift so they don't get separated.
You will want to keep a backup in case it does get lost.
