What about using Binance? Letting them register them and just send them a gift card? Look at the link below.
I didn't know Binance offers gift cards. The only problem is that new accounts have to undergo KYC now. So he would have to perform identity verification. Since I don't like doing that myself, I don't want to suggest that he does. Do you know any other exchange where you could purchase a gift card that doesn't require KYC?
Yes, any amount now on Binance that you will purchase now is required KYC and you will perform identity verification. Maybe other exchanges too but there's a limit before or a maximum limit that shouldn't exceed before they will ask users to undergo KYC.
I saw a thread of a list
Gift cards providers, it might be good if you will try the no-limit option there since you don't want to perform KYC verification.
Regarding your friend, IMO, isn't ideal to give a gift that they didn't know or familiar with, I mean a zero knowledge of what they receive and it seems it could be there will be a chance of possibility that it could be lost on their hand. However, if you will include a video tutorial on the gift that you gave to them on basic information towards how Bitcoin will use and keep it safe might be a good idea if you will force yourself to give something that they didn't know yet.
