I know the intention is good, but don't ever give bitcoin to anyone who doesn't understand it. The chances of it never being touched are high. My advice is, you hold the .3 for them, being someone who understands this technology and in the future when bitcoin and cryptos are more widely accepted you can show them then, how to spend it. No need to lead them into an investment mentality with this, investments are not spendable, bitcoin is.
I am recommending this same idea as this can more practical as we know that older people can have a hard time understanding cryptocurrency (though there are exemptions, of course). The same thing goes to parents who desire to gift their young ones with bitcoin...it would be better if they themselves are the ones holding the coin so it is safe and secured. The idea of gifting our loved ones with bitcoin or any crypto for that matter is something I do appreciate.
