Thank you everybody I have made the decision to make this thing reality, I've just created the wallet and printed 3 copies of it (1 for me, 1 for my nephew (that i'll give to my sister) and one stored safety in my loft with only my mother aware of the place ).

This is the address that I've made for him 18RRU9vusin5URqbW823jPrdAiAWtQ4zf1, now I only have to deposit the 0.1 BTC, but it lacks 1 month to his birthday so in the time remaining I'm trying to keep the 0.1 for me and trade it for cumulation.
If somebody of the new, wealthy elite wants to give to my nephew a little present all donation will be for Tommy (this is his name) and when it will be 18 years old would have an even greater surprire

Thanks for the advice man, one day I will let him read this conversation which I am sure will remain faithfully archived in this forum where everything was born <3
